F1 – MODULE IS RETURNING A GENERIC “CAN’T INSTALL MODULE” ERROR
Verify that the language and currency corresponding to the selected eBay marketplace are enabled in the Prestashop environment, for example if you want to install the module and use it in eBay.com,
the US (USD) currency and the US language pack must be activated before installation.
F2 – HOW CAN I CORRECTLY UPDATE THE MODULE FROM A PREVIOUS VERSION ?
If a module update is detected in your backoffice and your Marketplace account is enabled, you can proceed by clicking “Update” in the Prestashop modules list.
If you have a ZIP file containing an updated version, you can upload it using the “Add new module” feature of Prestashop (DO NOT UNINSTALL THE PREVIOUS VERSION as you will lose all the configurations already made).
After verifying the successful update (Prestashop must show you an update confirmation box in green), do the following to make sure everything will work properly:
– Verify that the module version (in Modules -> Fastbay) is the correct one (updated)
– Clean your Prestashop cache from Advanced Parameters -> Performance
– Clear / empty the cache of your browser to delete any obsolete content
– Enter the module configuration , check again all the values and confirm with a click on SAVE (at the bottom of first module tab) to complete the update.
