Using CiviCRM 4.6.9.

While exploring debugging options I clicked on "Yes" for the "Logging" option in the Administration "Misc" page. That created hundreds of tables prefixed with "log_" in the CiviCRM database. This isn't what I wanted.

I've turned off logging, but the tables are still there. Is it OK to manually delete any table beginning with "log_"?

Rob - yes you should be fine to do that. Backup prior of course. Is it the fact you have tables, or the size of them that is the issue?

  • Tables and data consume resources, so I would say that it's both.
