Slow site and multiple 500 Internal Server Error

Permalink
Hi All,

I'm having issues with concrete 5 over the last 2 days with a very slow site and multiple 500 internal server error pages. I havent really played around with the settings and i'm unsure what to suggest to fix it. I have read many forum posts such as deleting page statistics in the phpmyadmin but this also did not work.

the site:www.www.electrician2cardiff.co.uk...


Regards,

Dan

hello - is the site set up correctly on the server - if I go to that URL the site is for Vanda Coatings.

That aside - it does appear to be running slowly - if this has just started to occur have there been any recent changes made to the site?

You can turn off the page statistics collection in the admin side of the website which may speed things up a little for you.

Hi,

Yes - just using this to do development before the test goes live.

How do you turn this off on the admin side?

log into admin
Dashboard
System & Settings
SEO & Statistics
Statistics

and uncheck 'Track Page View Statistics'

I just had a look through the site though and did see a 500 error. There is also something a little screwy with domain name resolution going on with that domain - not sure what difference that would make though.

Thanks - Unchecked it - I havent noticed any change yet however.

Sorry - What do you mean by domain name resolution, how do I resolve this?

Another question - what do you suppose I should have cache settings on?

good question - as you are developing the site you generally would turn the cache off.

If you want to test the cache out then turn it on for everything - this should stop access to the database once the pages are cached (which may be where you are seeing latency).

I had a look at the homepage on tools.pingdom.com and got about an 11 second load time from Amsterdam (most local) for the whole page of 750k. Most of that time was the server waiting for a response to the first request.

Is this on shared hosting / VPS? Is the database on the same server? Most slow-loading I've seen like this come from resource issues (or maybe configuration issues) on the hosting.

I think it may well be to do with the hosting - Weirdly it happens at certain times, generally in the morning I dont have this issue. The hosting is with 123.

Is there any other things I could try before changing host?

Thanks for you help

you could go through the various best practices which ideally you'd do anyway.
Reduce all of your images
Combine javascripts and css wherever you can

check for duplicate scripts and resources - looking at the source of your page I can see you are loading up 2 different versions of jquery (I'm guessing to do with a plugin) - in fact the call in your footer looks to be incorrect.

That said all of these things might have minimal effect if it is the hosting/server that is causing the issue.

Is this testing environment just an interim measure or is it where you were hoping to run the site long-term?
