Pages are blank after updating PHP

[Convergence]

Greetings oh wise ones!

Last night I upgraded to PHP Version 5.2.6 on our server. It had some strange effects on Zen Cart installations.

There are over a dozen Zen Cart installs on the server. All but three are fine.

1. The three that are not fine all have blank pages throughout the catalog.
2. Can access admin, cpanel, etc - just can not see any catalog pages
3. Google can still access and download the sitemap.xml file - while I can not view the sitemap in the browser. Google downloaded it 7 hours ago and reported no problems.

All stores are version 1.3.8
All stores have the following add-ons:

1. Ultimate_SEO_URLs_v2.106
2. google_sitemap_1-3-19
3. easy_populate_free__from_langer__modhole_v1-2-5-5
4. zencart_zen_1-0 template

All stores have worked flawlessly until updating PHP

Tried to debug using step 2a
https://www.zen-cart.com/tutorials/index.php?article=82
but nothing appeared in the cache folder - permissions are set to 777

Went to 2b for debugging and received this:

Notice: Undefined index: seo_urls in /home/wallart/public_html/includes/functions/html_output.php on line 24

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 4980736 bytes) in /home/wallart/public_html/includes/classes/seo.url.php(1059) : eval()'d code on line 5462

Notice: Object of class queryFactoryResult could not be converted to int in Unknown on line 0

We are leasing a dedicated server, and the company we lease it from says PHP is working fine...

At a loss - one of the sites is a costume site and doing very well this time of year and we'd really like to figure this out

Any insight from the great Zen minds is appreciated.

Thank you!

The SEO mod appears to be the problem ... if you turn it off or remove it, do things work?

Hi Kim, thank you so much for your quick response.

Did disable the SEO mod - but that did not work.

Going to try to remove the mod now and replace with original files, original .htaccess where applicable.

Thank you again for your input.

Hi Kim,

Yes!!!

Removed the SEO mod on one of the stores - the store is intact.

Now to attempt to reinstall the SEO mod...

Thank you again!

Hmmm,

Reinstalling the SEO mod - didn't work - I'll have to figure something out. I have over 10,000 SEO'd pages on those three sites

Something must have been corrupted somewhere

Thank you again for your help!

Good News!

Some very technical folks who we lease our servers from reconfigured the PHP on the server.

All sites are back and fully functional without having to do anything to Zen Cart or the mods.

Now to build some more Zen Cart sites!

Thanks again Kim for your assistance.

I'm sorry I am unable to give you any more details other than what I put in my post...

As I am not the one who reconfigured Apache / PHP.

I suggest you contact the company who hosts your server.

Good Luck!
