it keeps loading if i try to save something

I got another problem.  I notice it keeps loading forever if i try to save it.... What does this mean?  Do I need to enable something or...?  

what the heck is going on?  Anyone can't login now.  It keeps saying.  

"Error!

Your username or password was incorrect. Please try again."

but it's not true.. I think the loading part isn't working.. UGH!  I'm starting to HATE webmin now!  Any ideas?

never mind.. it's fixed.  

And the cause was?

well... I found this from somewhere here and placed it in .htaccess and hoping it would run the site a bit faster.  I didn't know this was the problem.  I'm not sure why.  I used this.....

When apache was updated, those modules, mod_deflate and mod_expires may not have been installed, updated or activated.

I generally do not do upgrades to server software on a production server. Only security or bugfix updates via yum or apt_get depending on Linux version. It avoids problems such as the ones you had. So i only do it if it's absolutely necessary.

sigh yeah.. i learned my lesson.  i will never ever do that again.
