Another Plugin or Theme is using ‘lb_postrender_handler’ to handle output buffers.
This prevents actively outputing the buffer on-the-fly and could severely degrade the performance of this (and many other) Plugins.
Consider disabling caching and compression plugins (at least during the scanning process).
Hi, I now receive this error on all sites since the latest update? I have disabled all plugins, but still it happens?
A quick internet search for “lb_postrender_handler” shows that this OB Handler was most likely injected into your sites with malicious code. My plugin just detects any and all uses of named OB Handlers because of the potential for any of them to adversely affect the output on your admin pages, specifically the results of the scan. Therefore, this warning can sometime point to an issue that needs to be dealt with immediately. In this case it sounds like it is an infection that is now spreading to al your other sites, so you definitely want to pin down where it is coming from.
If you have truly deactivated all other plugins then my next guess would be that this malicious code has been added to your theme, although it is also possible that the code was injected into a WordPress core file.
Then next step would be to reinstall a fresh copy of the theme that you are currently using and the then reinstall the WordPress core files.
Just to confirm that this is your only course of action, I want to make sure that you have already run the Complete in my Anti-Malware plugin and that nothing was found, is that correct?
