Problems with links when migrating a site from multisite


I recently migrated a site, using snapshot, which was built on upfront spirit, within a multisite environment. I took it out of the multisite environment onto a single wordpress install, which I then turned into a multisite.

I found that the image url links did not update, so I used a plugin to change the addresses. This worked in the tables in php my admin, but I found that I had to manually upload a lot of the images and re-insert them via upfront.

I have since found that upfront is working very slowly and am concerned that something is still linking back to the old site.

When looking in PHP My admin I see that the minification chart table is still referencing the old url.

I would really appreciate it if a wpmu developer could take a quick look at the site and highlight anything I need to update.

Many thanks
