W3 caching plugin

Hi, can anyone shed any light on the best solution to the W3 caching plugin not working pleae ? There has been a bug for some weeks now, and the author of the plugin as no idea how much longer it will take to fix, and it’s actualy costing me business now. I am not at all technical so please could someone advise what I should do. Try a new plugin ? Disable this one ? I’d need to know what effect any actions will take on my site https://www.balletnews.co.uk and I am really desperate to get the site back to normal. The bug is really affecting it’s design. thank you
