Q. What does
Warning: fopen filename: failed to open stream: Permission denied mean?
A. When the message is associated with your
oik-bwtrace log file
then it means that the trace file is currently being used by another process
so the trace routine was unable to log the message.
The full message displayed is similar to this
Warning: fopen(C:apachehtdocsoikcom/bwtrace.loh): failed to open stream: Permission denied in ... wp-contentpluginsoik-bwtraceincludesbwtrace.php on line 690
Starting from oik-bwtrace v2.0.7 you can now choose to trace AJAX transactions separately from others. This can reduce the likelihood of getting this message when you’re tracing
