500 error when posting a link?

[Cryptophile]

When posting a link in a specific topic it shows a 500 error - I'm unsure why. Any ideas?

Edit: Disabling the link mycode get's rid of the error. - anyone have any thoughts on how to fix this and what exactly is the issue?

which code you have disabled ? is it regular link code of MyBB or custom MyCode added earlier ?

It was the link mycode but after disabling and re-enabling it a few times fixed it.

in general, we suspect mod_security (or suhosin security) for such issues
& latest entries of server error log needs to be checked to trace the cause of 500 server error
