Unable to add products or categories after 1.5.4 upgrade.

Site: https://www.torontoturbo.com
Upgraded to 1.5.4 a few days ago and everything seemed to be running fine.
Not exactly sure what my old version was maybe 1.4x
Now I tried to add new products or a new category and they do not appear after pressing the insert button.

They do not show up on my Admin or the live website.

Any Help would be appreciated.

What version of PHP is installed on your server?

I will have to check....not even sure how but I assume from the C-Panel?

Something that comes to mind is the old version had a file called ZC_admin and the new one was ZCadmin....without the dash (or visa versa). This is how the update was and not something I changed......might be a good spot to start?

Can I just change names? or swap folders if this is the cause?

You can check that from Zencart admin under Tools - Server/Version Info.

Did you update it yourself, or use your host's auto-install?

PHP Version 5.4.41
Should I change the file name zc_admin? or swap files?....not sure which one was the original now.

Yes I auto install from C-Panel

You should never use the auto-install function to upgrade a Zencart site. It's hard to say what may have been messed up. You may have to start over with a fresh installation of 1.5.4.

Do I have to delete everything or down grade?
What about saving all the -products and templates/pictures?

Try using the instructions at How do I rebuild my site on the new version, instead of upgrading? - Blogs - Zen Cart Support

Above is an image from my C-Panel showing the two ZC Admin files I now have after the upgrade.
The original was zc_admin....now there is a zcadimin.
Could this be the root of the problems?

Doesn't anyone think the problem is the mis-match in the naming of these files?

In a way yes as that seems to be an indication that ZC was installed by some automated process instead of as directed/suggested in this website...

Further as a result of said posting, it's probably a wise idea to change the name of the admin directory for all sites about which you are discussing away from either of those naming conventions.

The presence of two admin folders itself is not an issue. What is done to the database when using one or the other could be an issue. Thing is there also, if both directories now exist side-by-side then that is further indication of an install gone bad (by automation at that). Why? Because it appears that "unnecessry" files were not removed which means there may be files that if upgrading this same way manually should have been removed but still exist.. All sorts of things could be awry.:/
