advanpix on "[Plugin: WP QuickLaTeX] Cannot connect to QuickLaTeX server"

Hello!

I ran into the following problem:

*** QuickLaTeX cannot compile formula:
a^2+b^2

*** Error message:
Cannot connect to QuickLaTeX server: Failed to connect to http://www.quicklatex.com port 80: Connection timed out
Please make sure your server/PHP settings allow HTTP requests to exteal resources ("allow_url_fopen", etc.)

It never happened before. I have created a new site powered by wordpress with a new IP. The plugin works excellent on the new site. I came to the conclusion that the old IP was included in the plugin's blacklist. But I didn't do anything illegal (spamming or something like that). Please exclude my IP (81.177.165.71) from the blacklist.

Thanks

There were many attempts to crack the QuickLaTeX server from this IP (malformed requests with sql injection code, etc.)

I unblocked the IP for now. Please try it now.

But will block it forever if I will see stuff like this once again.
