Dear sirs,
I am reporting, that after today's plugin update to 3.1.2. I have got this error message on the updated WP website http://www.skidestne.cz:
ERROR: var_export(): Cannot use output buffering in output buffering display handlers
Until update previous version worked properly. The database is backuped but the progress stops at 25% at WP XML Export and restarts after 5 mins without success.
My job is set do not backup files (only db, Wp XML and plugins list), so max. latest successfuly backuped files are about 287 kB large.
Plain WP content XML Export (All - Posts, Pages, ...) from WP menu works in seconds and ok.
PS: I can forward my error log to an email, if it wont be well formated and readable below. Just ask for it.
Could you help me with this strange issue?
Thank you
Alois
