I have taken control of a website that has been functioning for several years, and in messing around I have noticed that there are many outdated plug ins and problems associated with that. I've come to the conclusion that all my problems could be solved if could update our site to the most current version of wordpress and update all the plug ins.
Past administrators bought a theme called CoffeeBreak 2.3. After viewing various forums, youtube videos, and self help sites.... I realized that the little button to update to the most current version (visible on those sites) is missing from my version, and I believe that this is because of the theme.
The problem is that I cannot remove this theme without completely messing up the current site and all of its content. Our organization has very important information for members and I can't disturb this to start new.
I've been told that the solution to this is to set up a dummy website where I can work on everything without messing up the current site, and then eventually replace the new with the old.
This is going to take a ton of added time and effort. If it is too much our org may have to hire someone to do all this. But if there is a better way, or another way to do it that is not as time consuming, please let me know. All I want to do is update to the current version of wordpress without messing everything up. Thank you.
