THIS  ERROR OCCURED WHEN YOU CLICK TO THE ” Page Layout and Site Template Settings” IN SETTINGS UNDER ” LOOK AND FEEL SECTION/CATEGORY “

RESOLUTION :

Edit using sharepoint designer open the site in SPD and then tried to add the .aspx pages in  “wt” library.

for that you have to open 2 sites one  which is not generating errors say sitecollection_945 in SPD and the other site which is genrating error as in our case is the sitecollection_946.

copy all the .aspx pages from folder _catalogs\wt\forms from the sitecollection_945 to the sitecollection_946 _catalogs\wt\forms then select the option of view in browser you can be able to see the pages now.
