Mysql cache?

I have just installed dolphin 7.1.6 on my new plesk server and not used to plesk ive never used it before really. After the install everything seems all ok except for when i install modules i get a 502 gateway error but when i refresh it does install the modules and got no probs with any modules chat is working fine aswell as the forums.

But...

I have 2 fails in the host tools section.

MYSQL

query_cache_size = 0 - FAIL (must be >= 16777216)

thread_cache_size = 0 - FAIL (must be > 0)

could this be causing the 502 gateway error? im unsure of how to edit these in plesk it was very straight forward in webuzo.

The only other things wrong in hosting tools are 3 undefined messages. Which is unusual because the modules are actually on.

rewrite_module - UNDEFINED

deflate_module Apache module - UNDEFINED

expires_module Apache module - UNDEFINED

would undefined modules be causing any problems?

Please use host the 100% support dolphin like www.zarcona.net.

The 502 error is from Nginx. Does it happen on the site or in Plesk only? Plesk uses Nginx, but Apache is the default web server. Your host will know more about the setup. I don't have much experience with Nginx.

You'll need to update the main MySQL configuration file - usually /etc/my.cnf - and change those values to:

query_cache_limit = 1M
query_cache_size = 32M

Also under Plesk > Tools & Settings > General Settings > Apache Web Server, make sure rewrite, default, and expires are all checked. If not, check them and save. Depending on how PHP runs on the server, Dolphin may not be able to see which Apache modules are loaded. If URLs work, then rewrite module is loaded.

Your host may be able to make these changes for you.

502 gateway error on a strict Nginx server usually means that Nginx can not talk to PHP.  If you have Nginx running as a proxy to Apache then I have not worked with that setup; I use Nginx as the direct webserver.  If you are not running Nginx or Apache then please tell us more about your server.

Thanks for your replies. I have fixed all the 502 errors. and 90% of the https problems. Once I updated MySQL the 502 error cleared all is good now.

I followed another members fix to get flash working with https ... the only problem I have now is everything works on https like chat and map etc but the orca forum buttons do not work still under https. Its pickled me a bit.

I did read there was another forum module about called pkforum but it is no longer in the market place? all the other mods work great on https now it is just the forum :S

Encrypting chat?  Are you running a top secret conference or something?  You don't encrypt everything!

@geek_girl

My whole site is https from the installation. I try to just do it where it encrypts only logins and tried a few codes to have it only https on certain pages with htaccess but having no luck at all. every code redirects to https or one code I put in htaccess works and chat/forum gets redirected to http and the pages are broken saying show all content.

So had no choice really.
