Hello all, I have same problem, as above, problem is I could use normally once installed latest version of LimeSurvey 190+ (fantastico), and suddenly today is not working! and can't modify previous entries as well.
after reading all about it through these forums, I have asked my host to disable mod_security for the domain, and they have done that. but problem was not solved!!! at all! there is nothing on the "+" or "-" signs, even mouse on them stay static withOUT hand courser, predefind lebels and quick adds also are not working , just no response at all from broswer! no error in the footer bar of broswer...
one thing i didn't try yet, is to re-upload files using binary, seems logic to me as i faced similar problem long time back with another web application.. BUT, which files i have to re-upload? as stated above, i have used fantastico, so i will download the latest version from Limesurvey website, but please tell me which files i have to re-upload in binary mode??
thanks a lot for all the efforts you are putting..
waiting for support to end this issue like the other happy guys
