Hi Denis,
The logo that did not show is the small limesurvey logo on the front page.
Yesterday I deleted and reloaded the latest version of Limesurvey (160204). I then could not see anything at https or
www.windsurfer.me.uk/limesurvey/admin
. There was nothing in the limited log files I have access to.
I could not find a php.ini as per the FAQs, so have contacted my web server host to check whether a php.ini that I cannot access exists, so I can check the variables and paths
I have just seen the new posts about version 2.5 problems, and will try the solutions over the week end. However, if the older FAQ tips still apply, I may need to apply those first.
