I have updated the plugin to the latest version 3.4.1, and when I try to translate a post that contains a repeating group it generates the following error:
'PHP message: PHP Fatal error: Uncaught OTGS\\Toolset\\Common\\Exception\\NotImplementedException: Not implemented. in /.../wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/DatabaseLayer/Version1/AssociationQuery/association_query_v2.php:1521\nStack trace:\n#0 /.../wp-content/plugins/types/application/models/field/group/repeatable/ItemPathBuilder.php(122): OTGS\\Toolset\\Common\\Relationships\\DatabaseLayer\\Version1\\Toolset_Association_Query_V2->include_original_language()\n#1 /.../wp-content/plugins/types/application/models/field/group/repeatable/ItemPathBuilder.php(83): OTGS\\Toolset\\Types\\Field\\Group\\Repeatable\\ItemPathBuilder->query_item_parent(67772)\n#2 /.../wp-content/plugins/types/application/models/field/group/repeat'
I automatically update all plugins to their latest versions. In fact, in version 3.3.13 it does work, as of 3.4. it no longer works.
It is impossible to give you a copy of the web, since it is a very large web that weighs a lot.
