CSS form builder and html editor error

Hello i think i found a very annoying bug on the css form builder 2 when i activate it to use html editor with file managment, already happening to me on 2 sites im building, after making the forms and selecting the field that contains the html editor selection file management then selecting which conection to use and then Allow access to option, if i have 2 diferent tables for example one for users and another one for admin panel, when i go and test the page and hit the icon called "insert image" it popups the image propertie box, in there i click on check on the server and there it throws me this error:

The server didn't reply with a proper XML data. Please check your configuration

i checked and compared to other sites i made with the only difrence that on the sites where it works fine theres only one tables that manages both users and admins and on the sites it doesnt work is where i manage independant tables one for normal users one for admins.

I manage to make one of the sites that had this problem work the thing is that i modify so much the code on the helper_PHP.php and HelperGroupsRulesPHP.php and html editor config.php spent the hole day testing and changing that i dont remeber what change i did made it work, but still i try to apply those files changing the callings for the other sites but still without luck.

Also testing the page i was login as an admin also tested as a user and so on have lost a hole day cause of this bug hope WA can duplicate the bug so it can get fix.

now the normal upload on the third tab of the image propertie box no matter what it never uploads the files i try to upload that way even with the html editor working check error-2.png it stays there stuck until i close that box and does not upload any picture

If there is any work around if these bugs are already known please let me know what to do im very frustrated with them.
