XF 1.5 Javascript error toggling smiley visibility

[m1ne]

I have a lot of smilies, and now I want to remove some.
When trying to toggle the visibility of a smiley or smiley category, I get this error,

The server responded with an error. The error message is in the JavaScript console.

How can I work around this? There's far too many to delete individually. I'd prefer to hide them, but deleting is fine too.

Thanks!

There was a php setting that frequently had to be set to resolve a similar issue when having to many smilies present and trying to delete them.

max_input_vars = 3000

is what I used (default is 1000).

3000 didn't work, but 5000 did. Thanks!
