Internal Sever Error – Admins only

Good morning,

I am at the end of my tether and I urgently need some assistance in rectifying this issue, which is now adversely effecting my business.

When my website gets busy (it seems to be when there is over 280 visitors on the site at once) as a logged in administrator I experience a number of issues.

– First of all the site becomes slow, images take a while to load in the gallery as the number of website visitors increases
– Then it will flash up ‘connection lost’ and I am unable to update the article
– Sometimes I can hit update, but then eventually it loads a ‘opps cannot be found’ page, or an internal server error
– Whilst there are over 250-300 people on the website I am unable to load any pages, update any articles.

The strange thing is, if I load the website in a private tab or on another device as a normal visitor, it loads instantly. The problem only seems to exist for logged in administrators.

I run a news website so as you can imagine, it is fast becoming a problem. Last night I reported a story which saw over 450-500 people on the website constantly for around an hour, later dropping down to 300, then 200 as the night continued. This issue means I cannot provide updates to the story, or publish any new stories that may come in.

Can anyone point me in the right direction here? Why is this issue only affecting logged in administrators? If it was a server load issue surely normal visitors would be experiencing problems too?

Any help much appreciated.
