    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 https://www.quicklatex.com port 80: Connection timed out
    Please make sure your server/PHP settings allow HTTP requests to external 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.

    Thank you very much for your reply.

    The plugin works very well now.

    But I am at a loss that the QuickLaTeX server was attacked from my IP. I work with wp-quicklatex for 3 years and I do exactly the same thing that I did 3 years ago. My site is about school physics and mathematics and it work for the educational purposes only.

    I changed my login and password and I hope this will not happen again.

    Many thanks

    Probably you need to check your site for trojans. There is a good chance it was hacked and now been used for sending SPAM or other bad things.

    There were a lot of attempts to hack the QL server from the IP – I have learnt a lot on hacking methods by just reading logs :).

    I am not very experienced with this though….
