I think it’s a Firefox problem. I can log in with IE, but not with Firefox 3.0.1. Try that, Zyama. * [mrkingid](https://wordpress.org/support/users/mrkingid/) * (@mrkingid) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808633) * I confirm that patrickd88. odd * Thanks for the heads up. * [patrickd88](https://wordpress.org/support/users/patrickd88/) * (@patrickd88) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808634) * Great. I really dislike IE. Maybe I can roll my Firefox back to 3.0. * [corymathews](https://wordpress.org/support/users/corymathews/) * (@corymathews) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808635) * Hum I thought it was an Opera issue because I can still login on FF3, * [corymathews](https://wordpress.org/support/users/corymathews/) * (@corymathews) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808637) * Nvm just log out if you are getting this problem then you are able to log back in. * [patrickd88](https://wordpress.org/support/users/patrickd88/) * (@patrickd88) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808638) * Cory, are you on the 3.0.1 build? * [corymathews](https://wordpress.org/support/users/corymathews/) * (@corymathews) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808639) * Nope just 3.0 FF isn’t my primary browser so im somtimes a week or so behind * [Jeffro](https://wordpress.org/support/users/jeffr0/) * (@jeffr0) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808656) * I’m using FireFox 2.0.0.15 and everything appears to have worked just fine for me. * 749387 * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808658) * hi, * i had the same problem since i tested all the wp 2.6 betas with firefox 3. i searched a lot an i installed firefox again, but nothing helped me. * the solution in my case was verry simple! * i cleaned all cookies in firefox and then i noticed, if i go to the adminpanel with the login link in the frontend of the blog, i have no problems with login. * i always go to the dashboard with a direct bookmark in firefox that was [http://myweblog.tld](http://myweblog.tld) and my solution was, that i write www. before it. so the link in the bookmarks in firefox was now http://**www.**myweblog.tld and now i have no problems anymore. * if you look at the saved cookies in firefox, they all have www. before, and so i give a try to make the same in the bookmark link and it works. * [ba78](https://wordpress.org/support/users/ba78/) * (@ba78) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808662) * Both with a clean, new install, and with an upgrade: K2 theme’s sidebar manager is not working. Consider it before you do an upgrade. * [UseShots](https://wordpress.org/support/users/useshots/) * (@useshots) * [18 years, 1 month ago](https://wordpress.org/support/topic/update-to-26/#post-808672) * There must be a problem with the new cookie system they intoduced in v2.6. And you seem to be unable to login if your browser still has cookies from the previous version. That’s why you manage to login when you 1. change a browser 2. clean cookies 3. add www. prefix if you didn’t use it. * I guess there should be 2.6.1 pretty soon 😉 Viewing 15 replies - 1 through 15 (of 40 total) 1 [2](https://wordpress.org/support/topic/update-to-26/page/2/?output_format=md) [3](https://wordpress.org/support/topic/update-to-26/page/3/?output_format=md) [→](https://wordpress.org/support/topic/update-to-26/page/2/?output_format=md) The topic ‘Update to 2.6’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 40 replies * 22 participants * Last reply from: [Samuel Wood (Otto)](https://wordpress.org/support/users/otto42/) * Last activity: [18 years ago](https://wordpress.org/support/topic/update-to-26/page/3/#post-809375) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
