Fatal Error message

Hi everyone,
When I click on the “The Look” in the Journal Management, I am getting this error message:

Fatal error: Cannot redeclare class ThemePlugin in /home/dbqedu/public_html/digitalud/ojs/lib/pkp/classes/plugins/ThemePlugin.inc.php on line 59

Also, I am getting this error when I click on Journal Management → System Plugins

What do I need to do to clear this up?

Thank you.

Hi @Jonathan_Helmke,

it sounds as if you ran into this error.

Hope this helps

The cause of the error will be similar to the thread @cjuergen pointed to, but in this case you will not be looking for a duplicate plugin. Rather, the base ThemePlugin class from the core product has somehow been duplicated.

Is there a second copy of “ThemePlugin.inc.php”, perhaps as “themeplugin.inc.php” in the same folder?
