IE Menu Bar -> Tools -> Internet Options -> Advanced Tab

Browsing Section (Probably Second Section - though I think it can be the first also depending on settings)

4th Option down - Should be checked
5th Option down - Should be checked
6th Option down - Should NOT be checked

I am assuming that your script errors are javascript. If they are PHP - disable error reporting in php.ini file on your server (no clue how you do it on shared hosting - probably in .htaccess - but its been years since I have messed with those kind of settings on an account level, so I dunno for sure)

If the above for JS doesnt fix JS problems - and you are using IE - not something else hosting IE - then I would look at re-installing IE - or reinstalling windows, as something odd has happened - or actually before that - I would go to Microsoft.com and find Windows Script 5.6, download, install - then if that doesnt fix - then try reinstalling IE - then if that doesn work - if its annoying enough (which if its script errors - it would be) - do a windows install, not an upgrade - choose the new install - then when you choose what drive - choose the current drive - do not repartition - then on the next screen - make sure you do not reformat (unless you want to) - it will just wipe out the windows directory, leave everything else intact - though some programs would have to be reinstalled to get the registry settings back.
