Hi,
Can you edit the language file under the languages tab of the HikaShop configuration ? At the bottom of the language, you have the version number of the language file:
HIKA_LANG_VERSION="6.2.0"
If this number is not the same or higher than your HikaShop version (which you can find at the top of the main tab of the HikaShop configuration), HikaShop will display that information message.
The en-GB language file is the only one included in the HikaShop install package. And when you update HikaShop, it automatically updates that language file too.
So normally, for the en-GB language file, it should always be synched with HikaShop.
Potentials reason I can see it why it wouldn't be the case would be :
- if you manually changed the version of the language file (with a copy/paste of the whole file content for example)
- if there are some permission problems which prevented the Joomla installer from updating the language file
I don't expect this to be a bug in HikaShop as I can't reproduce the issue on my end and no one else reported the problem.
