By disabling the plugin, making the changes, then re-enabling the plugin I never had any problems. I also deleted the cache after making theme changes and before enabling the plugin.

Never had any issues with editing posts/comments though? I don’t know if that will be of any help in the future for you…

So now, I think I’ll try Hyper Cache instead. Thanks for the input

Cache wise, I don’t actually use DB Cache any longer. The only reason being it seemed to stop tags from being saved on posts (and conflicts with the membership section I now have on my blog).
I’ve tried WP-Cache and Super-Cache in the past but both caused issues of their own.
My recommendation now goes to Hyper Cache, which also came out on top over at a roundup post on Tutorial9 (http://is.gd/dMpX4)
Obviously there’s no reason to switch from DB Cache if it’s all working for you, but a cocktail of DB Cache and Hyper Cache should ease the strain on your server if you’re having problems.

@David → Funnily enough, I just checked my cache plugin, and it wasn’t activated either, D’oh! It must have needed reactivating after the WP3.0 upgrade…not that any warning message alerted me (such as the SEO plug does).

I don’t use WP-cache any more though, as it stopped my RSS feed from working properly; I don’t know why. Instead, I use the one Chris Spooner once recommended on his blog – DB Cache.

Coincidentally, I read an email from ICDSoft yesterday saying my site was draining the shared server too much, and that I should use a caching plugin.

That’s when I checked and saw the WP-cache was disabled. Heh.

I made a few enquiries with ICDsoft after seeing David used them but all responses were not confidence inspiring.

I wasn’t keen on using shared hosting again and instead went to mediatemple’s DV server after Andrews recommendation. I work on my blog every day and have a number of external monitoring services and in my experience it’s been absolutely flawless for 7 months.

As Andrew says, the technical support is great. I called once regarding a simple security setting on MT as it was a little different to my previous host, and ended up having a 40 minute conversation with the guy about WordPress and his recommendations for a variety of plugins, security issues and solutions.

I’ve only ever had to wait a few minutes to get through to someone also, their DV service at least gets 10/10 from me.

I’m glad that Crucial Web Hosting worked out well for you, though

That’s my host for davidairey.com, and I use Crucial Web Hosting for LDL. Both are recommended.

MT’s support was quite good, however, their Grid server is always having some king of incident or downtime. I’m sticking with them as there DV servers are supposed to be top-notch, so I plan to upgrade within the next year. I thought web-site speed was an issue with the grid for a while, but after experimenting, I found it was all the larger social bookmarking buttons bogging my site it down, so I removed them.

Soon, their Grid-server successor “cluster server” comes out, so I may try this before a DV if its cheaper.

As a sidenote, MTs user interface is amazing. I tend to forgive their shortcomings when I’ve logged into my admin panel, lol.
