SERPOSCOPE - PHP Fatal Error: Cannot use output buffering

Hello,

I performed a new install of Serposcope 1.0.7 on Ubuntu 14.04 using PHP 5.6.14 and when running from command line "php cron.php"  I get the error:

PHP Fatal error:  Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

I tried changing my PHP directive from the default of "4096" to "off", "on", and back to the default of "4096" and this did not effect it (restarted server each time, error did not change)

I attempted to search forums but I did not see any solution to this issue.  Anyone know what I should check on my server that could cause this?

Thanks!

Re: SERPOSCOPE - PHP Fatal Error: Cannot use output buffering

Really strange error, I'm afraid I don't have a solution, you'll have to google for this specific php error : 'Cannot use output buffering in output buffering display handlers'

Or you can wait for serposcope 2, it will be released in ~ 1 month, it doesn't use this logging system anymore so it will be fixed.

Thanks for the reply,

Since I am new with this I was wondering if their are any debugging or additional logs I can enable or check to find more information?

Re: SERPOSCOPE - PHP Fatal Error: Cannot use output buffering

that's really strange, did you try to run from cli but not as root ?

Re: SERPOSCOPE - PHP Fatal Error: Cannot use output buffering

I just tried another user account and same issue, no change.   I tried another VPS all together on a different server with Ubuntu 15.04 & PHP 5.6 and I had the same exact error.

I commented out the ob_start line in cron.php to see if the script would run without it and it did.  It is checking keywords and scrolling the SSH session with the output with the ob_start line disabled. 
Is their any alternative way to make the output buffer work?

Re: SERPOSCOPE - PHP Fatal Error: Cannot use output buffering

well I don't know first time I see this issue... I won't try to find a fix because I don't maintain serposcope v1 anymore, working exclusively on serposcope v2.
