Oops! There's been a problem when upgrading Toolset data structures. Please make sure your current configuration allows WordPress to alter database tables.If the problem persists, please don't hesitate to contact our support with this technical information:
Changed type of wp_toolset_type_sets.id from bigint(20) unsigned to BIGINT(20) UNSIGNED Changed type of wp_toolset_type_sets.set_id from bigint(20) unsigned to BIGINT(20) UNSIGNED Changed type of wp_toolset_type_sets.type from varchar(20) to VARCHAR(20) Table 'db_dom25784.wp_toolset_relationships' doesn't exist Table 'db_dom25784.wp_toolset_relationships' doesn't exist Table 'db_dom25784.wp_toolset_relationships' doesn't exist Table 'db_dom25784.wp_toolset_relationships' doesn't exist Duplicate column name 'relationship_id' Can't DROP 'relationship'; check that column/key exists Duplicate key name 'relationship_id' The m2m-v1 database structure upgrade to m2m-v2 seems to have failed.
I have checked with my hosting service and they have confirmed that the current user does indeed have access to the database. They are saying this isn't the issue.
Thanks for the details, it is a known problem, I have escalated this thread to our 2nd tier supporters, our developers will take care it, it should be fixed soon, I will update this thread if there is anything news.
I have checked it in our to-do list, it is in the to-do list of Types plugin 3.0.1, which is not released yet.
And our Developer finalized a Beta version of Toolset Types that should solve this issue.
