Heads up! this post was created when Microthemer was at version 2. The current version is 7. Some references to the interface may be out of date.

Found this message today after upgrading to 2.4.7 but it could have been there earlier.

Warning: ob_start() [ref.outcontrol]: output handler ‘ob_gzhandler’ cannot be used twice in /home/fusionth/public_html/wp-content/plugins/microthemer/tvr-microthemer.php on line 240

Any clues?

Hi there,

This should be fairly easy to fix. Just go to the Microthemer > Preferences page and set the “Gzip Microthemer UI Page” option to No. This option speeds up the Microthemer UI page a bit when it first loads, but doesn’t provide any benefits past that.

If that doesn’t solve your problem please write back here and I will investigate things further in the morning.

Cheers,

Sebastian
