Seems like the last couple days there's a delay when navigating the site.

noticed it on my mobile and PC, home and at work.

I was just trying to post something on Politics and toward the end I encountered a delay of something like five to ten seconds between every three or four letters I entered.

Then when I tried to post it, it said the forum code is invalid.

I stripped out the forum code so there was no forum code and it still said that the forum code is invalid.

it goes is spurts.....sometimes fine, and then sometimes a couple second delay every time i navigate to a new page/link.

Definitely slower than it used to be recently.

Yep

Site has been slow on phone, tablet and computer.

We are currently investigating this.
