It’s definitely a cache-related issue but why and how do I resolve this from breaking again? It just broke again yesterday (broken captcha image). I had to go into LiteSpeed Cache plugin, purge the cache for it to work again.
I noticed that Yoast and Akismet Anti-Spam needed updated. Did that and the broken captcha image resolved. But…why? My client is concerned that this captcha plugin will break again the next time some random plugin needs updated. Do I need to keep checking wordpress daily for plugins that need updated so this captcha won’t break?
