Password-protected pages and Too many connections-error

Hi folks,

I am a total newbie to WordPress and don’t have extensive knowledge with coding. I have a website using wordpress (the installation was automatic through my web hosting service). In my website I have protected several pages (through wordpress editor) with the same password. That way visitors only have to type in the password once in order to see several protected pages.

Problem is: Every now and then I get a “Too many connections” error when I try to access a page that is protected. It seems that only a couple of simultaneous visits spark this error. Is there any way how I could increase the amount of allowed simultaneous views to password protected pages?

Many thanks!
