Title: Error with Jetpack Last modified: August 21, 2016 --- # Error with Jetpack * Resolved [Fionavar](https://wordpress.org/support/users/fionavar/) * (@fionavar) * [12 years, 1 month ago](https://wordpress.org/support/topic/error-with-jetpack/) * I have had to disable this plugin, as it reports the following error when loaded and seems to break Jetpack: * The plugin generated 2 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin. * Any advice or direciton would be helpful. I have let Jetpack know too. * [https://wordpress.org/plugins/rvg-optimize-database/](https://wordpress.org/plugins/rvg-optimize-database/) Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Contributor [cageehv](https://wordpress.org/support/users/cageehv/) * (@cageehv) * [12 years, 1 month ago](https://wordpress.org/support/topic/error-with-jetpack/#post-4843421) * Hey Fionavar, * When exactly do you get the ‘headers already sent’ error? While activating my plugin, while running my plugin, …? * Which versions of my plugin and Jetpack are you using? * I double checked and my plugin is not sending 2 extra characters. * I also installed Jetpack on one of my own websites and didn’t get any error messages, everything works fine. In other words: I was not able to reproduce the error. * Ciao!

Whereupon the stat graph for Jetpack is broken. What can I do to help? Plugin v: 2.7.7 * Plugin Contributor [cageehv](https://wordpress.org/support/users/cageehv/) * (@cageehv) * [12 years, 1 month ago](https://wordpress.org/support/topic/error-with-jetpack/#post-4843460) * Hey Fionavar, * Thanks for your feedback! * When you activate my plugin and you get the ‘headers sent’ error, to me it sounds like another plugin already sent the headers + extra characters, which prevents my plugin to be activated correctly. * Please try: * 1) deactivate ALL plugins for a moment and then activate only my plugin – does that give an error? does my plugin work? * 2) then, deactivate my plugin (so at that moment NO plugins are activated), activate JetPack, check of the stats work * 3) then, leave JetPack activated and activate my plugin too – any errors? Do both work? * Please let me know what happens for 1), 2) and 3) * Thanks!

Also disabled the Theme.

No matter whatever pattern I do this, the moment it is activated the error occurs. * Plugin Contributor [cageehv](https://wordpress.org/support/users/cageehv/) * (@cageehv) * [12 years, 1 month ago](https://wordpress.org/support/topic/error-with-jetpack/#post-4843494) * Hey Fiona, * Pffffhhhhh… tough one to tackle! * Fact is: +/- 50,000 users are using my plugin and hundreds of thousands users are using JetPack, so if there really would be a compatibility issue, I would have had many reports and complaints… but so far you are the only one. * Makes it look like it’s something specific for your setup. (Don’t get me wrong: I’m not blaming you for it! 😉 Just thinking out loud, trying to find out what the problem could be) * Okay, another thing you could try is to completely uninstall both plugins and then download and re-install both of them. * If that still doesn’t work we have to put WordPress into debug mode to see if that gives some more information… * But first try fully re-installing them and keep me posted. * Ciao!
