Our store is a combination of WordPress and Magento and we are upgrading to Magento 2 and I wanted to ask about someone else's opinion.
Is it best to choose a template for Magento store? if so what do you recommend? or should we update our previous theme which is ultimo and continue with that? I'm just trying to minimize the errors that we receive from Magento and run our store smoothly would this transition help?
Better continue and upgrade with Ultimo to keep errors under a limit. Although you'll face a few for sure which is unavoidable.
