PHP errors

Getting an error with your plugin recently, can only attribute it to the new WordPress release.

“[19-Aug-2015 17:58:38 UTC] PHP Warning: session_start(): Cannot send session cache limiter – headers already sent (output started at /home/XXX/public_html/wp-content/plugins/no-title-tooltips/no-title-tooltips.php:26) in /home/XXX/public_html/wp-content/plugins/count-per-day/counter-core.php on line 169”

I fixed it by removing the last two blank lines in the main file. If you could release a fix for this it would be appreciated.
