Good :)
Yes, you're on the right track.


That indicates that the db can't be connected. Specifically, when using the credentials in your admin configure.php the database isn't responding.

I have checked and double checked the Database username and password just to make sure everything is correct.

Can this be done? Since the database has been updated to 1.5.3. Can I upload the files from 1.5.3 and copy my configure.php files and my custom template over? I only have a couple of mods installed .

Yes, and that's essentially what I usually do when upgrading anyway ... my process is described here: http://www.zen-cart.com/entry.php?3-...d-of-upgrading

One other question I noticed the stylesheet.css and stylesheet_css_buttons.css were updated. I have my own template folder should I merge those 2 css files to my template css files?

You can certainly compare those files with the same files from the prior version (WinMerge is handy for this) and then make the corresponding updates in your own template.
In fact, that's what upgrading is about.

Thanks for all the help. I have reverted back to 1.5.1 for now. I have ran into one issue The admin area loads now, but the webpage is still blank. Any suggestions?

I have setup a test site and database for 1.5.3 and it is running just the generic Zen Cart stuff right now after I get the site back up I can start working on incorporating my live site into it.


Thanks,
Randy

"webpage blank" means that you've got a debug-log file in your /logs folder. Since it's an admin-related log (the characters -adm- will appear in the filename), make sure to obfuscate your admin-folder's name if/when you post its contents.

The latest error in the log files for admin was from 3 days ago (before I started the upgrade). I was a ZEND error php was changed to 5.4 and should have been 5.2. That has been corrected.

With the database being updated to 1.5.3 and I'm running 1.5.1 that should be an issue should it?

It is normally not recommended; however, in the case of running v1.5.1 against a v1.5.3 database, there should be no problem ... with one exception: any customer or administrator passwords that were automatically updated to more secure formats will no longer work if you're using v1.5.1.

Update.

First I want to thank everyone for their suggestions and help. Everything is back up and running. I wish I could be more specific in what I done to get it back up and running, but this is what got my website back up.

I started at the beginning I downloaded a fresh copy of 1.5.1 and started comparing and uploading files in the includes folder after each file I checked the website. I got lucky the auto_loader folder had the problem in it. I don't know which file it was since I uploaded the folder completely.

Even though this is a vague answer, I hope it can help someone else that has encountered the blank page problem.

Thanks,
Randy
