Error on encrypt library

[eluser]InterCoder[/eluser]
Hey guys,

Me again. I'm having a very strange error which is saying something about an encryption library. I'm not using any encryption functions and the error disappears when I press 'Refresh'.

This is the error:

What's wrong? Because, I'm not using any encryption function on that page.

Are you using encrypted sessions by any chance?

[eluser]InterCoder[/eluser]
Yes, but only in my admin panel.

EDIT: Sometimes the error occurred, sometimes it didn't.

It's a memory error, so I don't know what to tell you. If you can, get your host to increase the memory limit for php.
