I have (over the last 3 weeks) found all my sites that I have on a resellers package hit the 508 resource limit. There is no one common issue, such as a plugin that all sites use. I am at a loss!
The host suggests that I put the sites on a dedicated hosting but for all my sites this would cost a fortune. They are not heavy traffic sites (around 100 visits a week) and not massive number of pages (10).
One site that is happening to is not even live but is me refreshing, as I add content and change css!!
Is this an issue with the updated WP? I always keep WP and the plugins up to date.
Anyone else suddenly come across this problem. It has been in the last 2 weeks for me and happens all the time on multiple sites.
