Hi David,
I checked with the 1.9.44 version of Updraft Plus. Same problem, no change, I still get Page not found error when I select "Settings->UpdraftPlus Backups". I do not see any custom page for HTTP 500 errors on our website. So not sure what is getting redirected. Will try to get access to the PHP error log file.
Is there anything else you can suggest to get it working! I really want to use updraft plus for backups & restoration. I need to backup asap before making major theme change to the website! So please help.
Will purchasing the "Automatic backups" add-on make any difference and somehow fix this problem if I delete it and re-install after purchasing the add-on? Please let me know soon.
Thanks a lot for your help. Regards.
