Hi
I have read a lot of problems regarding missing graphs. Unfortunately all the solutions did not help me.
I have the following Problem: All graphs are broken with the error message
"The image xy cannot be displayed, because it contains errors". The generated file itself is not a valid graphic file because it has one empty line at the beginning of the file. I have not found the source of this empty line but removing it shows the graph.
So, my first question is: How can I prevent that each generated image file has an empty line at its beginning.
Secondly, the debugged graph show another error "Error: no permissions!". I have checked the user rights (Administration -> User -> User rights) - they show read/write to every item listed. All other tabs have "xx" in it.
The mysql user has full access to the zabbix database.
Second question: Why do I get a "no permisson" error. How can I change this permission for i cannot see how to grant this permission (even the Admin is affected).
My System Config:
f7, php-gd-5.2.2-3, php-5.2.2-3, phpinfo() shows gd module support enabled.
thanks in advance
