Answered Firefox stuck saving Resource

Hi There,

I have a fairly large site, which often hangs when I hit 'save' on a resource (using firefox). There's no way to cancel it, so I end up losing my changes.
I have several other modx sites, but it only happens on this one.

HAs anyone experienced this?
I'm assuming it could be a memory issue or something, but when I open it in Safari and save, it seems OK.

Really annoying, as i much prefer using Firefox.

Thanks
Andy

Have you looked at your dev tools panel to look at possible error before or after clicking the save button?

I haven't. I'm not sure how to interpret the data that would appear there though.

Hm. That would be the only angle I can think of right now to start debugging. Could also be there is no response at all or maybe a 500 error. Then you could compare if Safari and Firefox are sending the same sets of data.
If you get a response, the value returned could give you some clue.

Other than that I have no experiences with an error like that that could help, sorry.

OK - will have a go and see what appears in the dev tools

Any Firefox plugins that might be interfering?

Try repairing the table in the DB with PhpMyAdmin.

One final potential culprit, as always, is mod_security. In my experience, mod_security is responsible for the majority of cases where resources fail to save.

Thanks bob

No extensions - all disabled.
It's happening across multiple machines too.

Which table would I repair in the db?

What would I do with mod_security?

Thanks

Tables: Repair all of them. Select all and use the "With Selected" drop-down at the bottom of the grid.

mod_security: The only solution is to file a ticket with your host. They should be able to tell from their logs if mod_security is being triggered. As a diagnostic, you could try saving an empty resource repeatedly. If that hangs, it's not mod_security. Also, if the same resource that didn't save will save on subsequent tries without changing the content or TVs, it's not mod_security.

You can try watching the Network tab in Chrome Dev. tools when saving resources. When it hangs, you can select requests and look at the Response tab. You might see a PHP error there or some other indication of the problem.

Ok thanks - I'll do some fishing! Will report back if I find the culprit.

Hi again.
So I caught thew issue in the console on saving - but not sure what it means!
Obviously something to do with tinyMCE - but I've checked and it's the latest version.
