XF 2.1 Template modification switch broken

[Oblivion Knight]

I noticed yesterday that when I try and use the switch on any of my template modifications, I get an "Oops! We ran into some problems." error.

Unfortunately there is nothing to go on in the browser console, it basically reproduces the page source as a whole error.

I can disable them by going in to each individual modification and deselecting "Automatically apply template modification" which works without issue.

Aside from disabling all add-ons and re-enabling them one by one (I'm currently running 72 add-ons) to find a potential culprit, is there anything else I can try?

Thanks.

Does disabling all addons via config solve the issue?

Do you have a huge list of template modifications? As in, you'd estimate hundreds or more of them?

Yes.

On initial testing, it seems likely some kind of memory limit is being hit.

It's likely to be PHP's max_input_vars setting then, though it could also be one of the Suhosin settings, if you have that.

The relevant configuration value would need to be increased for this to work as expected with a huge page like that.

Upping max_input_vars to 1500 from 1000 solved the issue. Thank you very much.
