- Does plugin works with WPMU and WordPress MultiSite installations?
Yes. - After upgrade, my custom post types or taxonomies are not accessable for edit or creating new ones?
Most likely problem is that definition of post type or taxonomy is incomplete and some capabilities are not set. Review the settings for them and fill all capabilities. - Some of the options for the editing of post type (add new, edit…) are missing.
This usually happens if the capabilities for the post type are not set as they should. Open post type to edit with GD CPT Tools Pro, and on Advanced tab you will find basic capabilities and list of capabilities. If you don’t want custom capabilities, make sure that Capabilities are set to ‘Use Capability Base’, Capability base set to ‘post’ and click Auto Fill Defaults in the list of capabilities to have them all inserted. - PHP reports fatal errors with registration of post types or meta boxes?
Only one type of plugins are known to cause such issues. This is caused by W3 Total Cache or similar caching plugins when configured to use database and/or object cache. Both these features can prevent real time access to actual data in the database, and W3TC is serving cached data, and preventing plugin to add info to database or to get data when needed for proper unserialization.
