XF 1.5 Unable To Save Or Create Thread Prefixes (The server responded with an error)

[XxUnkn0wnxX]

Hi, I'm un sure to why this has happened, but out of the blue I cannot make new thread prefixes or save them any more

this what I get in my Javascript console.

https://gist.github.com/XxUnkn0wnxX/07ea3fbd72411e4cf22a0b19482735da

was to long to post here

the rest of the board functionality seems to work just fine, including java script just thread prefixes no longer working no matter what I do...

nothing seems to fix this, even after re-importing master data, server reboot, DB Repair & Optimise, Xenforo File Replace, All Addones Turned Off. Nothing works. while java script works fine every where else...

Edit: I get javascript error only when I select all boards, but if set to None saves/creates just fine.

I found problem, I only get that error if the total amount of selected nodes exceeds 1122

if I go above that I get that error. how do I raise the limit & Fix this?

I have a total of 1141 Nodes

You're running into PHP's max_input_vars limit. It defaults to 1000. You'd need to increase this in php.ini. (It's not something XF can change.)

is it safe to set this to -1 for infinite?

I would probably suggest only setting it to something like 3000 (and increase if needed).
