We are using OJS 18.104.22.168
When I tried to download the View report for one of the journals https://journals.lincoln.ac.nz/index.php/lr (Tools -> Statistics->View Report), it took ages and eventually I got an error message as below:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
I have the following PHP error in the logs:
PHP Warning: assert(): DefaultOverrideHeaderChildThemePlugin failed in F:\journals.lincoln.ac.nz\wwwroot\lib\pkp\classes\plugins\PluginRegistry.inc.php on line 228
PHP Warning: call_user_func() expects parameter 1 to be a valid callback, class ‘TinyMCEPlugin’ does not have a method ‘registerJSData’ in F:\journals.lincoln.ac.nz\wwwroot\lib\pkp\classes\plugins\HookRegistry.inc.php on line 107
PHP Warning: assert(): Assertion failed in F:\journals.lincoln.ac.nz\wwwroot\lib\pkp\classes\core\PKPRouter.inc.php on line 317
I can download all other reports and View Reports from the other two journals hosted by us, with no error message.
I tried to increase the php execution time to 300s, then to unlimited time, but still get the same 500 Internal server error.
What else could I try to solve this issue?
