Hi,

Thank you for this great ecommerce plugin.
I have a stage site on my subdomain, but when i move to the live site i get a Class J2Store not found error on the frontend and a 500 on the backend.
Any ideas? Thanks.

Hi Boudewijn,

it is hard to see what is going on, we do not have enough information at this time.

Any way you can edit this ticket and give us credentials we could use to get access? Thanks!

Olivier.

Thank you for quick reply Olivier
I have already installed a full Plesk backup and will try to uninstall j2commerce now and then move to top domain and reinstall j2store.

I still have the problematic zip backup, i can install for you on another subdomain.
Copying this backup over the Plesk backup is showing "Class J2Store not found' error and backend 500 error.
I managed to get rid of the first error when i put all j2store extensions to '0' in database, but error 500 persisted

Joomla 5.4
PHP 8.5.3
J2Commerce 4.0.0

Uninstalling J2Store, copy paste the whole site and database, reinstall J2store did the trick.

Ok, great, I am glad it now works for you.
