When editing a page in WordPress you have a choice between a Visual and a HTML editor. The other day I was amusing myself with hacking the javascript file (quicktabs.js) that controls what ‘buttons’ appear on the HTML editor. The javascript file is located at /wordpress/wp-includes/js/quicktabs.js
I also changed the gif that is used for the background of the tagbar (ed-bg.gif) which is located at /wordpress/wp-admin/images/ed-bg.gif
It works fine. It displays fine. in Opera, IE, Firefox and Safari.

but, when you view it in Chrome you get this ..

Note that in the first instance- Opera, IE, Firefox and Safari you can see added ‘buttons’ [table] [Vsp] [tr] [td] and it is surrounded by a blue field.
In the second when viewed in Chrome it is the default WordPress editor – default buttons and grey background.
What UP WID DAT?
What have I done to Chrome to try and resolve this?
1) Reloaded page several times. Nope … that didn’t work.
2) Went to ‘Clear Browsing Data’ and Emptied the cache. Then re-loaded the window. Nope .. no change.
3) Cleared EVERYTHING in Browsing Data. Then re-loaded the window. Nope .. no change.
4) Downloaded latest Chrome to Beta 2.0.172.27 … Nope .. no change.
5) Cleared cache in the Beta model. Re-loaded screen. Nope .. no change.
Now, I am stumped. Every other browser displays the page with changes except for Chrome. If Chrome failed to display the new buttons that I coded into the javascript file but displayed the bluish ‘surround’ then I would presume that it was a problem with caching the javascript. The problem with that being that the bluish surround around the tagbar is a simple gif stored at the location I mentioned above. I simply changed the color of the gif from grey to blue and uploaded it.
Any ideas?
