I get an error every time I try to access ("Files & Images") the assets folder. I have a fresh installation of 2.3.5, and I have not seen this before in on other sites using 2.3.4. I installed 2.5.5 again on a new sub domain to check it and it work at first but then produced the same error when I changed some of the files in the assets using my FTP client. I trued to change the files back but that did not work.
I have seen these posts http://silverstripe.org/upgrading-silverstripe/show/269536#post269536 & http://silverstripe.org/upgrading-silverstripe/show/255475#post255475 but these solution involve making changes to a sapphire file which I am not keen to do unless I have to.
I have attached the error and any help would be great.
Cheers
