Help me to solve this problem. I'm starting to use couchcms.
Hello and welcome.
This particular problem has been reported before and was traced to IonCube loader having some issue with PHP 5.4.3.
Anyways, this has been rectified. Please upgrade to the newer version of Couch available for download at viewtopic.php?f=5&t=7014 (the upgradation process is simple and is documented in a file named UPGRADE.txt within the zip).
Hope this helps.
