Ultimate SEO / SSU won't uninstall

A recent PHP upgrade activated an installation of SSU/USU and is now preventing the store from loading. The Admin area is accessible, but there's not a module listing within Admin > Tools. The site was separately migrated to a new Linux hosting plan using PHP 5.4 and MySQL 5.5 and the administrative area and storefront are both inaccessible. The migrated site was additionally updated to v 1.5.4 without any change. The database was further updated to reflect v 1.5.4 and it's just a WSOD on the storefront.

I reviewed the information in an old thread https://www.zen-cart.com/showthread.php?99317-How-do-I-remove-Ultimate-SEO-URL-completely without any further success. :blink:

Does anyone have any further suggestions? We're not quite at the stage of utilizing the SEO URL configuration, but if it can be uninstalled and then re-installed, that would work as well.

I appreciate any assistance in the interim. :D

It sounds like a number of things are going on here... A PHP version change, hosting change, Zen Cart upgrade, etc... What was the last thing done before the site stopped working?

Do you have a backup of the site from before the migration, upgrade, and other changes? Hopefully you do, but if not please make a backup of the files and DB now!

The preferred method of handling an upgrade is to rebuild on the new version. The fastest way to get everything working correctly may be to restore a backup. Then use this process (if it was not followed when performing the mentioned upgrades).

Simple SEO URLs and Ultimate URLs work very differently from each other... Which one is installed? What version of the module is installed?

Last but not least, please post answers to ALL of the questions in the "Posting Tips" (go to a notebook or desktop, click reply, scroll up, and read the posting tips). For example what DEBUG logs are being generated?

My apologies on missing the pertinent details. Here's the remainder of the information, as requested.

What version of Zen Cart are you using? v.1.5.1 for existing storefront, v 1.5.4 on separate Linux hosting plan
Has your site been upgraded? When? From what version(s)? The 1.5.1 site was to be upgraded today. On Wednesday, the PHP version was changed from the existing 5.2 to 5.3 without any effect to the storefront.
If you've upgraded, HOW did you upgrade? (official upgrade procedure or an automated script from your hosting company?) On the separate hosting plan, the existing site was upgraded through an automated script.
What plugins/addons have you installed? When? If your problems are payment-related, what payment module(s) are you using? If it's shipping-related, which shipping module(s) are you using? USPS API module is in use, USU was previously uploaded in January 2015 but installation was not completed.
If your problems are language-pack related (non-English), have you checked that all the language files are loaded and correct? No.
HOW did you install Zen Cart? (upload via FTP and run zc_install, or a one-click install from your hosting company? (one-click installs might mean you don't have enough information about your site/server to make customizations easily)) Original install was a one-click install, zc_install was required to complete initial database on cfg file upgrades to v 1.5.1 as existing install was 1.3.x at the time.
What version of PHP and MySQL is your server using? (See Admin->Tools->Server Info) PHP 5.3.24, Zend 2.3.0, MySQL 5.0.96-log
WHEN did the problem "start"? Friday, not provided with actual "start" time.
How does that compare with other events of your hosting company, changes you've made to your site files/addons, or your admin settings, etc?
Please post the contents of related "debug logs" generated by Zen Cart

[06-Jan-2016 15:47:06 America/Phoenix] PHP Fatal error:  Multiple access type modifiers are not allowed in /home/content/m/i/k/mikeluna/html/ZenCart/includes/classes/ssu/cores/parser.php on line 10
``` This is the only debug information that appears from the date/time specified  and the file is replicating every 2-7 seconds.
    If this is your first store, have you tested all aspects of transactions before going live? Yes
    In what ways is your site customized or different from a brand new uncustomized install? Custom image on storefront header, background changes, storefront width modifications, side boxes modified.
    Please post your site URL* so we can take a look at it. This is especially important if you're encountering display/layout problems, so the problem can be seen directly.
    Site URL = store.swherb.com
    If you're encountering problems that could be related to your server or hosting company, include the name of your hosting company (not their URL). GoDaddy
    HAVE YOU LOOKED IN THE FAQ AREA for answers to your question? (ie: a search for your error message or what you want to edit/change, etc) Yes, I read every link available and the steps provided in all active and closed threads did not resolve the issue.
    Have you searched the FORUM for your error message or for answers to the question you're asking? Yes.

the existing site was upgraded through an automated script
Is the existing site loading??
Is the install on the separate hosting plan loading? How was this upgraded?

Based upon the previous posts, it sounds like you currently have TWO websites hosted on TWO different hosting providers. Site A = Zen Cart 1.5.1, one-click install, Simple SEO URLs. Site B = Zen Cart 1.5.4, one-click upgrade, Simple SEO URLs. Neither site has Ultimate SEO URLs (does not use the file causing issues listed in the DEBUG statement). Is this accurate?

Are both sites encountering a "blank screen" with the posted error message? Or just one of the sites?

If you are not already using SSU on site A
I would not install SSU on site B right away

I would recommend starting the entire upgrade over (clean filesystem and clean database). Do not use any "one-click" method, instead follow the instructions to Rebuild on the new version of Zen Cart.

If you want titles / names in the URLs on site B... Long term, you may wish to look into using a different plugin to generate alternative URLs. I would suggest looking at either CEON URI Mapping or Ultimate URLs. Both of these are compatible with newer versions of PHP and work with Zen Cart 1.5.4. You could also contact the maintainer of SSU for Zen Cart 1.5.x and investigate the continued use of SSU (understanding the last maintainer has at the time of writing stopped distributing the plugin for free on zen-cart.com and requires registration with their "company" to obtain new versions).

If you are already using SSU on site A
Others have posted after making sure SSU for Zen Cart 1.5 is installed... One can delete the word "protected" from line 10 of the file listed in your DEBUG logs. This should hopefully get site A back up and running (if it is not).

I would recommend starting the entire upgrade over (clean filesystem and clean database). Do not use any "one-click" method, instead follow the instructions to Rebuild on the new version of Zen Cart.

If the installed SSU is an older version adding "anchors" such as "-p-7" or "-p-7.html" on the end, you can install Ultimate URLs on site B (as both plugins use almost the exact same "anchors"). CEON URI Mapping could also be used on site B, but would require a little more work to manually map the old URLs to the new URLs.

If the installed SSU is a newer version NOT adding "anchors", one could install CEON URI Mapping on site B, but remember to manually map the old URLs to the new URLs.

Alternately one could also contact the maintainer of SSU for Zen Cart 1.5.x and investigate the use of SSU on site B (understanding the maintainer *at the time of writing * has stopped distributing the plugin for free on zen-cart.com and requires registration with their "company" to obtain new versions).

NOTE: Just a FYI, few on this site will recommend using a "one-click" install or upgrade. Most will advocate using the process outlined in the Zen Cart documentation and in the article How to rebuild on the new version of Zen Cart. This is especially true if the site has modifications / plugins (including themes).

Just an update on the uninstall...

The entire site, including admin backend, is now resolving to WSOD.

I am working on the clean install option as I type this.

Hopefully, I get the customizations and database history to transfer. There's over 500 active products and I'm a little worried about not being able to get the storefront active again.
