Example
The image on the right is an example of an error message. Basically it is a dump of the call sequence'
In this example the error was created deliberately by loading an incorrect version of the jDownloads Komento plugin!!.
Remove or disguise the site reference as indicated opposite
Then copy the entire report as text and report in the Forums either as a post in Bugs or in a Private Message (PM). Sending an image version makes tracing more difficult!
.
Restore Settings to default
When you have finished looking for the 'fault' remember to turn off the debug settings!
When you have posted in the forum please remember to deactivate ALL the debugging setup. Leaving debugging on will slow your site down and probably confuse your users!
