I recently migrated a site from a Drupal 6 install to a fresh Drupal 7 install.
I then installed panels 7.x-3.5. Initially I had an older version of ctools installed, so I had to upgrade from 7.x-1.4 to ctools 7.x-1.6.
I then enabled panels the panels page is not showing up in "Structure". I checked permissions and all the correct permissions have been added.
I then try to flush my cache, and i get this error:
Fatal error: Class 'panels_renderer_standard' not found in C:\wamp\www\projects\elaw\sites\all\modules\panels\plugins\display_renderers\panels_renderer_editor.class.php on line 8
Here is a picture of the error with a full stack trace:
I can run cron just fine, but trying to clear the cache gives that error. In the modules page "Panels" is enabled.
Before upgrading ctools, I had saved a files/database copy and then tried removing panels from "modules" and adding Panels 3.4 instead. I got the same error.
I then restored my files and database and tried it again but with upgrading ctools instead as mentioned above.
There was also this error that briefly flashed up when I was enabling the module from the "modules" page, after the ctools upgrade.
I was able to get the cache to clear by just hitting reload. But, if after the cache clears I try to clear the cache I get the same error. Now the "panels" shows up in Management->Structure, but it has a strange error on the top of the page:
Notice: Undefined index: rows in page_manager_panels_dashboard_blocks() (line 1251 of C:\wamp\www\projects\elaw\sites\all\modules\ctools\page_manager\page_manager.module). Warning: Invalid argument supplied for foreach() in page_manager_panels_dashboard_blocks() (line 1251 of C:\wamp\www\projects\elaw\sites\all\modules\ctools\page_manager\page_manager.module).
Notice how none of the predefined panel pages are showing up?
I hit clear cache a couple more times (with it giving the "class panels_renderer_standard not found bug each time I cleared the cache initially and it clearing after I hit reload), and now the panels page is showing the Predefined Panel Pages, (user page, etc):
I tried creating a new panel page and got this bug:
I can't seem to create a new panel page.

I had an idea that perhaps it was a contributed module that was causing the error. I was going to just randomly start disabling contributed modules but I thought I would start with any contributed module that had ANYTHING to do with panels. I found that disabling "Panels Translation" in the "Internationalization" section fixes the problem.
I'm not sure why this was causing the problem, but after disabling it I no longer get the " Fatal error: Class 'panels_renderer_standard' not found" error. I am also able to get further in creating new panel pages. I get all the way up to saving and it gives this error:
I have verified that that table is not in the database....
I am on a very tight deadline and would appreciate anyone's insight. Thanks very much for any help.
