Today I updated my Q2A answer site v 1.6.3 to v 1.7.0-beta-1 and I have several problems. (http://www.wikifirst.net/)
1. After I signed as Admin found that Layout, Posting, List, Plugin, Moderate, Hidden tabs are not working.
2. Text editor is not loading
3. Top scoring users page and badges page are not loading
When I try to visit Layout, Posting, List, Plugin, Moderate, Hidden tabs I received following error message
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
but I can visit other tabs under Admin.
Please help me to solve these problems.
Note:- After I contact my hosting provider I received this information
"PHP Warning: require_once(/home/users/web/b2300/ipg.wikifirstnet/qa-include/plugins/qa-event-limits.php): failed to open stream: No such file or directory in /hermes/bosnaweb07a/b2300/ipg.wikifirstnet/qa-include/qa-base.php on line 718"
