Hi Chris,
Please delete this stored procedure - dbo.ProductLoadAllPagegNopAjaxFilters!
It will be created again when you install the Ajax Filters again.
Hi Tommy,
You need to run the upgrade scripts for each nopCommerce version one by one. But you also need to run our 7Spikes upgrade scripts for each version after the nopCommerce one. For example, run Nop upgrade script for 3.3 and then 7Spikes upgrade script for 3.3. Then do the same steps for 3.4 etc.
There is no need to uninstall any plugins. Actually you should not uninstall any plugins as this way you will lose their data in the database.
You can find all the upgrade scripts: nopCommerce + 7Spikes for each version of nopCommerce since 2.65 in the link below.

Just start from step 9. nopCommerce-upgrade-3.20-3.30.sql and run the rest of the scripts one after another.
Hope this helps!
