Our firm's WP theme is Halsey and the company that hosts it maintains functions that we can't get into as they are the admin. We can upload content. They chose this theme when they created the website and informed us a few months ago the developer is not supporting it anymore and our website needs an upgrade due to glitches, responsiveness, etc. We have tons of pages on our site due to the content we put up. They want to charge us by the word/page etc to upgrade to a newer theme and this can take weeks to convert. We want to make sure all other options are out before we consider a huge price tag. We tried to reach out to Halsey/CMS masters support and no luck. We're a small firm and have very little experience with any of this. Any suggestions would be greatly appreciated.
