Hi,
this is properbly a newbie question, but I can’t set the “Default Theme” in my database (Application) back to “Server default”.
I had a working application with xPages.
Then i started to try “Themes”. I created a new one “OneUI” from Declan’s example and I have set it in the “Application Properties” in the “Default Theme”-field.
However it broke the display of the “Rich-Text” and “Date-Picker” on my xPages.
So I decided to remove it. I deleted the “Theme” design element and set the application property back to “Server Default”.
But this did not work 
My RTF-components are still “ugly”. I can still see that some additional CSS-files are included. (The ones mentioned in the deleted theme. Even if i create a new blank xPage and insert one component (date picker) its display is broken.
If i create a new database on the same server, and create the same xPage in there, everything looks fine.
How do I set the application property “Default Theme” to its former state ?
Thank you in advance.

Subject: Switching back to the default server theme shouldn’t be a problem…
…though if you find it’s not working for you here’s a workaround:Open the Package Explorer from the Java Perspective and launch the xsp.properties file from WebContent\WEB-INF on the application.
And here delete the line ‘xsp.theme=###…’

Hi, thanks again for your help.
I have found the file and it was completely empty.(At that moment the “Default Theme” was set to “Server Default”)
I then tried to set it to a theme “xxx” and then it appeared correctly in the file.
Even after deleting this line the problem did not went away. So i guess that it is not a problem with the setting of the default theme.

Never mind. I already copy/pasted all design elements into a new blank database and there it works fine. (If i did a copy of the “broken” database or even a “Desing Refresh” then the problem was transported into the target databse.)
Maybe i have changed some other setting, which i can’t remember.
Nevertheless i am now up and running again nicely, so for me there is not much need to examine it further. Only in case that you would like to find the case of this then let me know and i will send you the application :-)))

Subject: You deleted your browser cache after you changed the theme?
Subject: same problem (updated)
Hi,
I worked with a database for a while and tried to play with the themes and got the same issue. Tried to edit the xsp.properties, tried with different machines and browsers (with deleting the cache) still the same. Any ideas aside from creating a new db and copy all the design elements?
After deleting all the themes the design reverted to the server default, but if I copy them back everything is messed up again. It looks a setting is stuck somewhere, but haven’t found any trace of my theme names.
As a side-note, theme resource files are not replicated for some reason.
UPDATE: I think I’ve found a solution, delete your theme file(s) and then create new one(s) and simply copy the content of the original(s).
