Rev 2.2.7 > Manager > Pkg Mgmt page blank after upgrade, getting a js error

Post 2.2.7 upgrade I am getting a blank screen when I click on Package Management.
Using web developer tools I am getting a JS error:

[13:24:56.128] TypeError: Ext.ux.Lightbox is undefined @ http://www.iowalug.com/manager/?a=69:26

in /manager/index.php on the Ext.us.Lightbox.register method call ...


I've tried several things, wondering if this was not specifically the issue but a symptom of something like a permission issue. As I investigated I thought it may be that the manager wasn't able to write a file or something. I also ran into an error at one point in the Minify ext when it was calling is_file( ... ) ...

So I may have a couple things going on, is what I'm getting at.

I had trouble start as I was removing some contexts and resource groups. I'm still learning MODx and had created those to try some things. When removing I may have had a couple wires cross. I did the 2.2.7 upgrade to do it, and hoping it would resolve the is_file error I was hitting.

sorry if that is all a bit "all over the place"

Have you tried clearing your browser cache? Sometimes lingering cached JS files from the previous version can cause issues.

I have.

Not sure how I've made a mess, but I've tried to run setup again a couple times ... install results in PHP warnings about mkdir and not having permissions. I'm hosted in a shared environment, so I even ask tech support to set appropriate permissions on the MODx directories to hopefully clean up what ever I did.

So along with that type error above I'm also getting a 500 error on this

http://www.iowalug.com/manager/min/index.php?f=/manager/assets/modext/core/modx.view.js,/manager/assets/modext/workspace/package.browser.tree.js,/manager/assets/modext/workspace/package.browser.panels.js,/manager/assets/modext/workspace/combos.js,/manager/assets/modext/workspace/package.grid.js,/manager/assets/modext/workspace/package.windows.js,/manager/assets/modext/workspace/package.panels.js,/manager/assets/modext/workspace/package.containers.js,/manager/assets/modext/workspace/provider.grid.js,/manager/assets/modext/workspace/workspace.panel.js,/manager/assets/modext/util/lightbox.js

just before

Uncaught TypeError: Cannot call method 'register' of undefined

which is on the line here:

Ext.onReady(function() {
MODx.defaultProvider = '1';MODx.provider = '1';MODx.providerName = 'modx.com';MODx.curlEnabled = 1; Ext.ux.Lightbox.register('a.lightbox');
MODx.add('modx-page-workspace');
});</script>

... All of the files listed in that GET are on the web server in those locations

I may just pull it all down and reinstall clean ...
