When click "All Pages" and "New Page", show us "Something has gone wrong. We've run into a problem and are unable to handle this request right now. Please check back in a little while." https://yourdomain.com/index.php?p=/pagessettings/allpages
Thank you for using Basic Pages! What version of Vanilla are you using? Please add this line to the /conf/config.php file to see details behind the "something has gone wrong" error: $Configuration['Debug'] = true; Please share the error message details here.
Thank you so much for your help @R_J , It fixed the "Something has gone wrong." problem, however, when I click the "new page" or "All pages" in the admin panel then it is showing this page "View not found. The view you were looking for could not be found."
