Hi,
Whenever I attempt to install or activate an addon I get:
“Error Oops, something went wrong (error). Please try again.”
It's not a very infornative message, so how do I find out why I get this error, and how do I fix it?
You will have to look at the AJAX response in your browser's debugger. I'm guessing some addon is generating a PHP error and this is coming back in the AJAX response but can't be parsed by the javascript that reads the response.
This type of error notification introduced does not help to debug the errors.
In most cases these are php errors, so you need to examine your add-ons.
Thom - if “display_errors” is on, the PHP error will be in the ajax response and it is that notice that I've found usually causes the “Opps”. It could be many other things, but that's what I've noticed the most.
