 * See on other websites, not sure how it was resolved. Now only on one website.
   
   The table exists. Its happening at all times of the day. I cannot find any reliable
   solution from other posts. Is there a known cause for this, and a way to work
   out whats triggering it? Then a way to resolve it?

 * Hi [@lencw](https://wordpress.org/support/users/lencw/), thanks for getting in
   touch with the detailed report.
 * As you may have seen from other posts, we have seen one case resolved as it was
   [an issue with the customer’s load balancer](https://wordpress.org/support/topic/commands-out-of-sync-can-we-get-a-resolution-please/),
   but have never received enough logging information to confirm the same cause 
   in other occurrences.
 * We are sure that MySQL/MariaDB is stopping, reconnecting and leaving the connection
   in a state that somehow causes this query error to appear. When sent error logs,
   we also see the exact same entries but with other plugin tables sometimes being
   the cause so believe it’s likely that there’s a database problem causing this
   behavior.
 * If you haven’t exported data from **jwl_wfblocks7** to confirm there are no copies
   of post data somehow in that table, you could, but we think it’s a problem when
   the query is being processed. You could also try repairing the table.
 * Finally, you and/or your host need to check the database server logs, other logs
   for the website(s) on the server such as syslog etc. to see what else is going
   on with the server at the timestamp of these issues. I would expect to see a 
   problem where the database is unavailable temporarily either because it is restarting
   or has crashed.
 * Let me know what you find out!

 * Peter, thanks.
    The table didn’t need repairing, also got hosting company (who
   are very good) to check logs, thats currently in progress. LenW

 * Thanks for the extra information [@lencw](https://wordpress.org/support/users/lencw/),
   let me know how that goes and hopefully can shed some light on what’s causing
   the database to stop. Tickets are typically left open on the forums for 7 days
   with no responses, so we’ll leave this open in case any further information comes
   up in that time.

 * In the MySQL server logs we are seeing:
    “Got an error reading communication 
   packets” at the same time as the errors in the wordpress error_log. The wordfence
   table error coincides with a database error which has a reference to the Divi
   builder (standalone version, not the theme). It happens on the live server, but
   not on a server with a copy of the website. Currently checking MySQL settings.
   We suspect it might be max_allowed_packet, connect_timeout, interactive_timeout,
   and wait_timeout settings. However, we are unable to identify whats happening
   at the time of the recorded errors: front end user or admin user, its not creating
   an order as times don’t correlate.

 * Hi [@lencw](https://wordpress.org/support/users/lencw/),
 * Did you find any further information about what was happening at the exact time
   the error was thrown? It looks like you’ve gone quite a bit further into this
   than we’ve managed to get information on before and it does go some way to explaining
   a database communication issue as we had expected.
 * Thanks again,
 * Peter.

 * At the same time as wfblocks erros the there are 2 other database out of sync
   errors relating to:
 * WordPress database error Commands out of sync; you can’t run this command now
   for query SELECT option_value FROM jwl_options WHERE option_name = ‘_transient_timeout_et_builder_ajax_cache’
   
   WordPress database error Commands out of sync; you can’t run this command now
   for query SELECT option_value FROM jwl_options WHERE option_name = ‘_transient_et_builder_ajax_cache’
 * However Elegantthemes suggest disabling plugins etc, but this is on a busy live
   site.
    I have a copy on a different server, and there are no errors. Currently
   checking server config differences live to copy server.
 * We still cannot identify whats happening at the point of the errors. If divi 
   builder related, it could be an admin task, but we doubt it due to the time and
   limited admin access.

 * Its not resolved!
    We have now upgraded this website to Wordfence Premium. What
   does the jwl_wfblocks7 table do, what happens if we delete all records, can ew
   do that? What will we lose? Thanks

 * Hi [@lencw](https://wordpress.org/support/users/lencw/) !
    Did you manage to 
   solve this problem? Did upgrade the wordfense plugin help? Best regards, Vadym.

 * No, these errors are still there.
    Software up to date, server checked, php 7.4.
   Other plugins looked at, nothing appears to change. Still sort of random, in 
   that when these errors appear cannot relate to any specific activity. This is
   a site with lots of regular traffic. LenW

 * Continues here too, though as many as 7 or 8 days can pass between instances 
   sometimes (though there is no set interval, and they can happen frequently).
 * For us, it began about a month ago soon after installing Super Page Cache for
   Cloudflare plugin, which may or may not be coincidental. Due to how complicated
   it is to configure, I don’t really want to uninstall it to find out.

 * These errors are beyond cool, but in case we’d rather not have them anymore, 
   any realistic solution on the horizon?
