Permission Errors

I keep these pop ups that say stuff like undefind1undefined. I have fixed some of my file permissions and this has stopped but I don’t know if the file permissions are correct. I set the permissions according to the installation instructions and it still gave some of my folders wrong permissions. How can I do my installation so that the empty popups and permission errors can be avoided in the future?

Ensure permissions are set correctly on include/jsLanguage/en_us.js and/or cache/include/jsLanguage/en_us.js

Thanks,

Will.

I have the same problem, but don’t have either of these files, I don’t even have the directory include/jsLanguage/. Any ideas much appreciated!
