I’ve checked the entired blog and everything looks normal. Otherwise if you want to waste some time you can downgrade to previous version of wordpress. * You can check both my blogs ([Casas Rurales en Granada](http://www.casa-rural-granada.es) and [Boat Charter Ibiza](http://www.charteralia.com/en/) ) and see for yourselves that the warning line is gone from the top of the home page. * 🙂 * [ramesh tiwari](https://wordpress.org/support/users/ramesh-tiwari/) * (@ramesh-tiwari) * [12 years, 7 months ago](https://wordpress.org/support/topic/wp-37-update-problem/#post-4261043) * Hey josefsp, Please i have same problem my client is very angry on me. i got smae thing When I open a pop up window I get the following: * [ramesh tiwari](https://wordpress.org/support/users/ramesh-tiwari/) * (@ramesh-tiwari) * [12 years, 7 months ago](https://wordpress.org/support/topic/wp-37-update-problem/#post-4261044) * HI alearango, * Have u got solution please share with me * [Sophie0503](https://wordpress.org/support/users/sophie0503/) * (@sophie0503) * [12 years, 7 months ago](https://wordpress.org/support/topic/wp-37-update-problem/#post-4261046) * Hello, * I have been experiencing some issues with the 3.7 update, as well. * Most annoying is that since the update, I am having issues with the visual editor when adding content to my site. Particularly when adding images – which, prior to the recent update was a very simple process. Now, when I add an image to a post, the image does not appear in the visual editor. Instead there is a large block of light blue at the top of the page above the body copy. The image does appear in the text editor and on the site, but any revisions to the alignment or caption of the image can only be done in the text editor. this is a major pain for me, as I am not adept at HTML code. * Any advice would be greatly appreciated … thanks! * [WPyogi](https://wordpress.org/support/users/wpyogi/) * (@wpyogi) * [12 years, 7 months ago](https://wordpress.org/support/topic/wp-37-update-problem/#post-4261047) * [@sophie0503](https://wordpress.org/support/users/sophie0503/) – that’s a known bug – see: * [http://wordpress.org/support/topic/problem-with-image-captions-after-37-upgrade?replies=80](http://wordpress.org/support/topic/problem-with-image-captions-after-37-upgrade?replies=80) * [WPyogi](https://wordpress.org/support/users/wpyogi/) * (@wpyogi) * [12 years, 7 months ago](https://wordpress.org/support/topic/wp-37-update-problem/#post-4261048) * **[@ramesh](https://wordpress.org/support/users/ramesh/) tiwari** – if you need more help, please start your own thread – as this one is marked resolved already.
