I just updated my wordpress to the very latest version 3.3.1. To my surprise this time it doesn’t go smooth as usual. I’ve got an error Call to undefined function is_rtl().
I can’t login to the admin panel once the update process completed. After few minutes of research the error is caused by a wordpress plugin. But how do we know which ones that cause those error?
Well here’s some step that you need to do to identify it
- Open up your ftp program
- Rename the plugins folder to something else (you can rename it to plugins_old, this will disable the wordpress plugin on your blog)
- Then you can login back to your wordpress dashboard
- Go back to your ftp program, create a new blank folder named plugins.
- Copy each plugin one by one from the plugins_old to the newly created plugins folder
Try access your dashboard back, if its okay then the plugin you just copied is working fine and not the one which caused the error.
Do it all until you find the one that you looking for. Once you find it the dashboard will be on crazy mode again. Just go back to ftp and rename the last copied plugin.
I’ve found that popup domination are the one who caused the error for my blog. So how about you? Found any other besides popup domination plugin that caused the same error? Share it in the comments. So others can save some time and straight away rename particular plugin instead to find it one by one.
