J2Commerce (formerly known as J2Store)
On update to 3.3.6
Starting from the release 3.3.6, when you install the latest version of J2Commerce on your site over an existing version, you might find a warning that looks like this:
Why does it occur?
This is just a warning. This warning indicates that there is already an existing version of J2Store available on the site, and now a new version has been installed over an existing version.
Will this harm my site?
No, this warning wouldn’t affect the site in any way. As mentioned before, this is just a warning, and you could ignore this.
Due to the backward compatibility to earlier versions of PHP
Sometimes, you could find a warning like this on your site:
Why does it occur?
This warning occurs when you turn on Error reporting on your site’s global configuration under System > Global configuration > Server tab.
This occurs since we provide backward compatibility to the earlier versions of PHP.
Will this harm my site?
No, this wouldn’t harm your site in any way. To overcome this, you could turn off the error reporting under Joomla! global configuration.**

Issue:
Unable to save anything on the site
This might be because of two prominent reasons.
Database type
The database type should be set to MySQLi (the one that is supported by J2Commerce) under System > Global configuration > Server tab.
Caching
This issue might also be because of caching. Try clearing the cache and disabling the site, browser, and server-side caching, if an,y and then try saving the settings.
