Well, hmm, I suppose we could try blocking mode and see if that works. I'm not exactly sure what could have caused the failure. However, I have received similar errors before.

[jacobsantos]

Any more information on what the problem is or possible fix? I would like to see this corrected.

[DD32]

It hasnt happened again, I suspect it may have been caused by my ADSL droping out mid-connection.

Errors should be prevented from appearing if WP is installed in an offline situation, such as a intranet though.

[jacobsantos]

Well, I think it is strange, since unless WP_DEBUG is turned on, fopen shouldn't send any notices or warnings.

Need more information before continuing. Reopen if more information becomes available.
