New to WordPress. Chose a theme that I am not crazy about. How hard is it to just up and change themes? Do I need to re-create Galleries, Home Page, About page? Page titles? Image titles, captions, alt tags and description? Will I generate 404’s? What about permalinks? Basically will I screw up SEO for my existing site, or negate all the work I’ve put into building current site.
I wish the answer was simple. It really depends on the theme you’re currently using. If the theme you use has galleries built in, then switching themes likely means you’ll lose them. But if the galleries are using a plugin, like NextGEN Gallery, then they will transfer to any theme since it’s a plugin. Page content should also transfer, unless you’re using a theme which has a page builder built into the theme instead of a plugin.
Thanks Scott. Current theme has built in galleries. As long as the images are still in Media Library shouldn’t be a problem to rebuild them. Think I’ll wait for a long weekend to try the switch and this time I’ll choose a theme that does not have built in page builder.
