Question in regards to Upgrade Instructions

Step 1: Disable the showcase addon
Step 2: Unpack/Extract the contents of the Zip file.
Step 3: Upload the contents of the upload folder to the root of your XenForo installation.
Step 4: Upgrade Add-on in the Admin CP using the provided XML file.
Step 5: re enable the showcase addon
THEN do step 6 and ignore the parts that I forgot to remove that mention re enablbing.
Step 6: Perform all of the post upgraded steps listed below

Post Upgrade Steps (run these prior to re enabling showcase

Step 1a: Go to Showcase Options (ACP >> Applications >> Showcase >> Showcase Options) and SAVE! This will stop any errors pertaining to options from being thrown.

Step 1b: Check ALL of the Showcase Options (ACP >> Applications >> Showcase >> Showcase Options). There are a couple NEW options and options that have changed. At the minimum, double check and SAVE regardless if you changed anything (so it sets the new options)

Step 2: Edit ALL of your categories making sure ALL of the settings/options are CORRECT. SAVE (regardless if you changed anything) to make sure the new options are set in cache)

Step 3: Run all of the Showcase Rebuilds (ACP >> Applications >> Showcase >> Showcase Rebuilds)

Step 4: TEST and make sure everything is functioning as it should. Once satisfied, re enable showcase.

NOTE: There are numerous template changes with this new version (as expected). If something is not displaying correctly, you may need to revert the template and then reapply any customizations (as some merges may not work).

 

You really don't NEED to disable, I just suggest it because if you don't and people are on the site, the error logs will fill up fast (specially if its a Major Update).

 

not really, because admins can still navigate the site and they can click on addon related links that would throw errors.
