re: FULLTEXT notices
The FULLTEXT notices are nothing to be concerned about. You are seeing these because the table engine does not support FULLTEXT search queries. In instances like this Connections will fallback to a more simple, though less accurate, search method.
More can be read about this in this forum thread:
re: No editor could be selected. **
You are receiving this error from WordPress because it seems the **GD image processing library is not installed and is required. Older versions of Connections utilized third party image libraries rather than the core functions provided by more recent versions of WordPress so there was not a way to report this before.
The solution is to request that your host install this very common (nearly always installed by default) image processing library.
WordPress will function without this library… sort of. It will not be able to scale and crop images in order to create the thumbnails of images and such. Instead what it does is use the full size image and force it to use browser scaling which is bad for your page load time, bandwidth usage and image SEO.
I hope that helps!
