Hi,

Thanks to enable the debug mode and set the error reporting to "maximum" in the Joomla global configuration and give us the error returned.

With the warning given, we don't really can define from where the problem come.

Hello,

I have activated the DEBUG system setting.
**Joomla! Debug Console**
**Session**
**Profile Information**
**Memory Usage**
**Database Queries**
**Parsing errors in language files**

JROOT/administrator/language/en-GB/en-GB.plg_content_jefaqpro.ini : error(s) in line(s) 63

**Language Files Loaded**
**Untranslated Strings**

The error is not in HikaShop but in Joomla.
Hard to say why you get it.
However, it is only a warning, not a fatal error.
So if you don't notice any strange behavior besides the message, you can simply turn off the error reporting of the joomla configuration and you won't get it.
