[TYPO3-english] White Screen Backend After phpMyAdmin Extension Install

[chris keithley]

To migrate my website, I tried to install the phpMyAdmin extension over a version that was giving me a "The mbstring PHP extension was not found" error. Immediately after I installed the phpMyAdmin extension, my backend went white and I cannot access typo3. The website is still up and running though. How can I repair my backend and have a working version of phpMyAdmin again?

Upgrading phpMyAdmin will not fix missing php modules.

Most certainly you just have to clear some cache, depending on your TYPO3
version:

4.x: typo3conf/temp_*.php
6.x: typo3temp/Cache/*

Thanks. I had a backup of the temp files and uploaded them to the typo3conf folder and I was back up and running.
