includes/class_dm_pm.php(599) : eval()'d code how can i fix that

Look for a plugin/hook that makes use of the pmdata_postsave_recipient hook and disable it.

You have a plugin hooked at one of the hook locations in the mentioned file throwing some kind of error. So, open that file, look at all the hooks within it, and check to see which plugins you have hooked to any of them.

What is the actual error?

i have nothing that use class_dm_pm

Opening the file as I suggested, I find the following hooks:

• pmdata_start
• pmdata_presave
• pmdata_postsave_recipient
• pmdata_postsave

Check any plugins with those PHP plugin hook locations for the error. :)

have nothing
