Description
When I'm going to: admin/reports/graphs images doesn't exist.
When I'm going manually to: /graphstat/history_graph_users or /graphstat/history_graph_nodes etc.
The page is empty.
What's wrong?
#1
I've got this error in watchdog:
call_user_func_array() [<a href='function.call-user-func-array'>function.call-user-func-array</a>]: First argument is expected to be a valid callback, 'graphstat_render_graph' was given w pliku /home/sites/co.uk/public_html/includes/menu.inc, linia 348.#2
I've cleared the cache and error disappeared, because probably after upgrade.
But images still doesn't show up, because contain errors.
The reason can be, because Devel show some html tags at the end. See attachment.
It's possible to turn it off without disabling Devel feature?
#3
Disabled Devel and still testing...
And it's because headers for images are in text/html format:
<img height="300" width="500" alt="Number of Nodes (last 2 weeks)" title="Number of Nodes (last 2 weeks)" src="/graphstat/nodes_graph_nodes_details"/>etc.
