I did took xoopseditor folder from xoops 2.2.3, did place it in /class/xoopseditor folder (I had to create it as it was no existing), then in my upload.php of the xcGal module I replaced /include/xoopscodes.php with /class/xoopseditor/xoopseditor.php but nothing, I just got an error as in line 129 there we have xoopsCodeTarea("caption",37,8); which seems is not existing in the xoopseditor :(
any advice ?
