"!Invalid Equation" displays
Hello! This issue just started this morning. I write SAT Math questions and solutions for my company's WordPress website and any string of math characters in CodeCogs Equation Editor longer than 2-3 displays and copies "!Invalid Equation" to the site. It has also converted every instance of LaTex I've written for the site to "!Invalid Equation". Any help would be appreciated, thanks!

Hi Codecogs team,

One of our users has been reporting Invalid equation messages since the 10th of May, and it is still experiencing them as of today. The last equation she was unable to use was:

\left ( 5,-4 \right )

I tested the same equation on my laptop and it worked, but she even provided a screenshot to prove it.

Any ideas of what might be happening?

We are receiving the message INVALID EQUATION as soon as we insert some mathematical equation in fx in the editor. We type the following:

π r^2 l

and we got the output "Invalid Equation". It was working fine till day before yesterday. Please guide us to resolve the issue.

Hi! Having the same issues as the others. Getting the message "Invalid Equation" in red letters in a yellow box in the display field when I enter only a couple characters in the generator field. Unable to type equations on my WordPress site, please update with any info, thanks!

Same issue. Please resolve this on priority. It was working fine a few days back.
