BUG REPORT Blank Error message when saving changes in CMS

[vish93]

Maybe you can check /data/other/logs/errorlog.txt ?

Good shout and as suggested just did this but weirdly last log is this:

[29-Mar-2016 11:33:33 Europe/Berlin] PHP Warning:  simplexml_load_string(): Entity: line 1: parser error : Start tag expected, '<' not found in /Applications/XAMPP/xamppfiles/htdocs/GMS/admin/inc/basic.php on line 291

Notice how the date shows '29th March 2016' could this be a clue ? am I being a paranoid over-thinker? I have recently updated xampp to the latest too, cant remember the date all that too well, but was around that date. Could it be php version 7 causing an issue, maybe a new simplexml is needed ?
