Until yesterday, this plugin runs very well on my blog. But, yesterday, my pages with inserted code have this problem:
Fatal error: ob_start(): Cannot use output buffering in output buffering display handlers in ../www/blog/wp-content/plugins/q2w3-inc-manager/q2w3-inc-manager.php on line 1135
The other pages are not affected.
It seems to me that the problem comes from the update of Advanced Custom Fields. So I desacvated that plugin, but this can't resolve the problem.
Please help me!
The php version of my server is 5.4 (defined in .htaccess file).
In my wp-config.php, the 'WP_MEMORY_LIMIT' is 256M, and "WP_CACHE" is set to "true".
