I've tried a fresh install (copied all folders and config-files from the stable release [I've also tried the GPL-Release], leave the original configuration, excepting the MYSQL-Database which i left from my configuration).
But the html-editor never seemed to work - it's still the same problem.
During installation i only get the following error:
MDB2 Error: not found (-4): no RDBMS driver specified
Error connecting to database: MDB2 Error: not found
I don't think, that this has anything to do with the html-editor.
The installation-screen (
http://server/roundcube/installer) said, that every dependency is installed and only displays the error according to the Code above.
There is another strange behavior:
If I compose a text-Message (by choosing "Text" in the dropdown-Menu on the bottom) I can write the message as usual (with linebreaks).
But the sent message looses every "newline"-character (only text-characters and spaces are shown).
