We have migrated the limesurvey to the new server and now everything works fine, but ther is a one problem.
I can't upload images to the survey (it happens in every single survey).
I could easily write it in the Source mode, but i still need to upload them to the survey. Is it any other way to do that? or how to fix this problem of missing uploading window?
The version of LimeSurvey is no longer in development.
I gues you use Chrome as a browser? Check with a different browser. The KCFinder (which is a thirdparty code for uploading and choosing assets like images) might not be working with newer versions of Chrome. Since you're moved to a new server the PHP setup and libraries might changed too. So KCfinder might is missing some php libraries too.
