## Summary
The root cause of this problem wasn't found. The 'quick edit' worked, and venues could be saved that way. If others experience this problem I'll be happy to help you debug it.

If you find the venue isn't creating, check you are providing the venue with a name!
If it's telling you venues are saving but they don’t appear – look at the top right of the venue admin page – does it indicate the correct number of venues? If so, it is a collation issue – this seems to effect only a few people, and I’m not yet sure why. The problem is probably that the collation of the slug column of the *_eo_venues table is not the same as the slug column of the *_terms table. You should use phpmyadmin or similar to change the collation of the former to the latter (usually they should both be UTF8_general_ci).
