Sometimes it can happen that after an installation of a new OpenCart extension, you will see following message:
Notice: Error: Could not load language module/languageManager! inBeside this, the new extension will not be displayed (e.g. in the module manager).
..\myshop\system\library\language.php on line 39
Well, basically that has 2 reasons:
- you have disabled or - very bad - deleted the english language (and all files)
- your newly installed extension does not have a language file in the language the shop has defined as standard (backend / admin)
What can you dow?
Open your FTP-client, direct to the admin language folder and open there the folder the new extension belongs (e.g. modules).
Copy the language file of the new extension into the language folder of the as standard defined language.
That should solve the above mentioned error and your new extionsion should be displayed (e.g. inside the module manager)
