The same behaviour occurs for every property page. The problem is a generic one, not related to php interpreter
I managed to minimize the scenario : 1. Open "Project Properties" (not Preferences) 2. Go to 'PHP Interpreter' node. 3. Check the 'Enable project specific settings' CheckBox. 4. Click on 'Apply' and 'OK' 5. Re-Open "Project Properties" (not Preferences) 6. UnCheck the 'Enable project specific settings' CheckBox. 7. Click on 'Apply' and 'OK' You should get an exception message to read within the log file.

The bug source is Eclipse. (see #137398) For some reason , when unchecking the 'Enable project specific settings' CheckBox and pressing apply, it removes a node from Preferences and then the workbench looks for a node which does not exist ==> throws Note : you can repreduce this bug also in JDT in the exact same way. *** This bug has been marked as a duplicate of 137398 ***
