Hi thanx for the answers.
The version is 3.2.1 the update is downloaded but still to do.
I haven't updates yet as the first thing supports ask is have you made any changes? Gives them a possible excuse to blame the changes/updates made.
Extensions: pages and lightbox.
I do check and optimized the tables in the DB regularly.
It didn't happen slowly, all has run well over several years but 8-10 days ago I noticed that members were double posting and new posts/reply took ages. The first thing I did was to check and optimized the tables. I then contacted support:-
support wrote:I see that currently our server on 10.169.0.65 is experiencing load but it is not critical. If you wish I could migrate your database to another server.
Migration made no difference and when contacted again their response is "There are no issues with the DB servers at the moment"
It is difficult to get past their first line of defence [support staff] and as it happened overnight and no changes were made to the site all I can put it down to is a problem with the DB server.
