I installed your plugin, and try to use it. but when trying to create a mailing list to work with it further, the plugin produces an error message:
The log file contains the following text:
“19-09-2017 17:29:12 – FATAL – m: 3.4 MB, u: 1 –
19-09-2017 17:29:12 – FATAL – m: 3.4 MB, u: 1 – SHOW FULL COLUMNS FROM
Can you tell me what’s wrong? Also what it is necessary to make, what to correct an error and normally to use a plug-in?
version of the plugin: 5.0.6
