Fixing the “Please Wait” error with Magento when Adding/Editing Products and Categories

I’ve been working extensively with Magento in the past few weeks and while it’s an amazing e-commerce system, their support and documentation is pretty terrible. A common error with the past few versions (I’m using is that the page freezes with “Please Wait” showing when you try to add products to categories, or add/edit categories themselves. Some users have also reported the same issue when uploading images or adding/edit products themselves. These are some fixes that people have suggested. If you’re having trouble, give them a try and leave a comment if you want me to add a fix to the list.

1 . Try a different browser

This fixed the problem for me, as I was using Firefox 3.6 (OS X) to access the admin backend, and switching to Safari 5 (I’m guessing Safari 4 would work also) fixed the issue. I tested this on IE7 (WinXP) and it also worked.

2. Disable mod_security and add whitelist

Check your mod_security audit log and if you see entries from the admin backend, have your host investigate and temporarily disable the module. If your issues goes away, ask your host to whitelist your admin backend.

3. Check your www vs. no www redirects

Make sure you’re only using one form of redirection, either in cPanel, Magento, or .htaccess. See this post for in-depth instructions.

Hope these help!


  • It was ‘mod_security’ issue for me. Works now per you suggestion.
    Really appreciate it.
    Thanks a ton & have a great day 🙂

  • For me, it was the .htaccess https redirect, which I had to comment out. This can be simply replaced by defining a https URL in the Magento web settings as both secure and unscure URL – that’s it!
