Hi,
I have accidentally deleted directories from the Oracle product directory. "C:\Oracle\product\11.2.0\dbhome_1\". I cannot recover them. I don't remember well what I destroyed.
Now the problem is that when I launch an application developped with the Universal Them (42) it appears like this :

I think this comes from a css style problem, because when I display the html file page, the source code appears. If I run older APEX applications not developped under APEX 5.0.3 with the universal theme, they appear well.
In the Application Builder, I tried to create a theme from the repository, but I cannot see any "Standard themes" in the drop down list. If I click on "All theme", I see theme from number 1, to number 26. It seemes Standard themes are missing. And Universal Theme of course.
I need to recover a proper installation of APEX 5.0.3.
I tried to reinstall it using apexins.sql, but it refuses saying "Error: This version of Application Express is already installed (APEX_050000)."
I am running APEX 5.0.3 with Oracle Database 11.2.0.1
How to repair the installation of APEX 5.0.3 ?
Best regards.
