I have searched the error message but nothing of the 8 available claims a case similar to mine, so I decided to write here.
My OJS version is hosted at http://www.ejtcs.org, and when I select http://ejtcs.org/index.php/A or http://ejtcs.org/index.php/A/index, the following error appears:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Web Server at @domain_name@
I can solve the problem by editing the last portion of the URL and entering "user", and everything goes back to normal.
I am also getting the same error when I try to change the language from English (default) to Turkish.
I appreciate your help on these topics.
