How to detect malfunctioning plugin

[voter]

Since some time I need to disable my plugin/hooks to be able to change anything in Style templates.
Is there any way to find out what is reason and which plugin results to this mulfunction without switching off each plugin separately.

For example
Pressing "save" or "Save and Reload" for template Editor which calls script

PHP Code:

css.php?do=edit&dostyleid=5&group=0&dowhat=templates&colorPickerType=0 


brings empty page with Style Manager on top and changes are not taken.

After disabling all plugins it works normal.
I foud that in my case it was vbOptimise guilty https://vborg.vbsupport.ru/showpost....&postcount=186


But, I wasn't getting any errors generated in apache/php logs with details what's going on...

It comes oft, that this or that plugin is not working and I would be thankful for ideas how to have more debug/error messages helping to detect malfunctioning plugins.

Usually there is an error which points to a particular hook location and that will help you narrow down which product/plugin is the culprit. But, if you don't have that, then it really is a matter of turning one off, seeing what happens, trying another, seeing what happens, etc.
