If you’re experiencing any strange behavior – missing posts, content that appears to be cached despite having cleared and turned off caches, etc – it’s possible that the storage engine of your database may be to blame.
When MightyBox creates a new site, it does so with all the proper database configuration in place. Some migration plugins, however, will change important database settings – namely the storage engine of a table – to something incompatible with Galera database clusters.
This can be confirmed by visiting PHPMyAdmin and reviewing the structure of your tables. If any are found to be something other than InnoDB, please contact MightyBox support so we can assist you with correcting the issue and restoring normal database replication functionality.
