Uncaught TypeError: Cannot read property 'opera' of undefined

I have a clean 7.1.4 install in a sub directory. I moved it to the root and now I get this JS error.

When you moved it, did you remember to edit the /inc/header.inc.php file to point to the proper root?

And did you empty the /cache, /cache_public, and /tmp directories (except the .htaccess files)?

Yes, the header is pointing to right root. I emptied the cache several times. Error occurs when you click login on the home page. No popups.

Here is the URL adventurousbug.com 

To be clear, did you empty those directories manually via FTP? Sometimes the administration panel doesn't do it.

If that didn't work, try disabling JavaScript compression (and possibly cache) from Administration -> Tools -> Cache -> Settings. This will rule out corruption from bad cache.

I used the panel. I tried to disable the compression. then used the admin panel to clear. still the same.

If I was to delete the cache via FTP would be in the cache_public directory correct?

After I turned off the JS and CSS caching, I got this error

FTP in, delete all files in the /cache and /cache_public leaving the .htaccess file in place in each directory.  Clear cache all in admin a few times.

The directories are /cache, /cache_public, and /tmp. But it doesn't look like this is caused by cache now. Try replacing the contents of /inc/js with files from a fresh download that matches your version.

deleted everything except the .htaccess file in cache, cache_public & tmp. Also replaced the inc/js directory from freshly downloaded 7.1.4  Still the same issue.

Weird everything else seems to work just fine.

New lines for errors

I was going to point out the non-standard jQuery in your /plugins directory, but it looks to have been removed while I was in the middle of testing. I'm not seeing any problems on the site now.

I edited the jquery.dolPopup.js and commented these lines out. The popup now works, but when I login the domain.com/member.php is blank. I have to go to the home page, refresh to show I am logged in then click the Account link and then domain.com/member.php displays my info.

I can't believe how fragile this framework is. You touch one thing and the wholesite is down.

//            if(!$.browser.opera) {
                iTop = ($(window).height() - $el.height()) / 2;
                iLeft = ($(window).width()  - $el.width()) / 2;
//            }
//            else {
//               iTop = (parseInt(window.innerHeight) - $el.height()) / 2;
//               iLeft = ($(window).width()  - $el.width()) / 2;
//            }

Try undoing those changes (or replacing the file). This looks like it was more likely caused by the extra jQuery being called. If you didn't delete it, I don't know who did.

For the blank page, that means a PHP error has occured. Check the error_log file under /public_html.

Hi Nathan, can you give a bit more info on what you mean by "extra jQuery being called" ?

How would I go about tracking what is missing or what was deleted?

Thanks.

Dolphin ships with jquery; it is used for many areas of the platform.  Dolphin already loads a version of jquery and loading it twice will cause errors.  If you add jquery code from the net, the instructions will usually tell you to load jquery; that is not needed as Dolphin has already loaded it.  When you load two copies or more, you will break jquery.

Could permissions on the directory be an issue? My sub directory was 755, the root is 750.

Note the date - it's from a few days ago. Do you have an error from today or yesterday? If you want, I can take a closer look - PM me the site and Plesk login (I'm guessing it's Plesk based on the path and timezone warning).

Replaced the /inc & /plugins folder from my original installation download, deleted all the files in the /cache & /cache_public folders and it worked. I will do some more testing and will post my final result.

Thank you Nathan & Geek Girl.

All tested and working. This thread is closed.
