Troubleshooting Website Cache Issues: My Experience and Solutions
I noticed that some of the pages on my company's website were not loading or displaying properly on different devices and browsers. The issue was random and didn't affect all pages simultaneously.

To address the issue, I used Google Search Console's URL inspection tool and the Google Mobile-Friendly Test to analyze the website pages. Based on the results, it seemed more likely to be a caching issue rather than a rendering or display issue.

I cleared the website cache using the "WP Fastest Cache" plugin, which resolved the display issue. However, this wasn't a permanent solution as I couldn't clear the cache manually every time. So, I suggested to our company's website developer that they look into the issue.
Unfortunately, I didn't get a solution from the web developer. So, I started to investigate the source of the cache issue by looking at various factors such as plugins, the theme, and responsiveness of the website design due to multiple plugins and widgets.

Finally, I coordinated with the web developer and gathered information from WordPress community forums and support. We worked together to resolve the issue by removing suspected plugins one by one and requesting version updates for the theme, WordPress, and other plugins. We also discovered that the mega menu plugin was not compatible with cache plugins, so we removed "W3 Total Cache" and "WP Super Cache" and used only one cache plugin, "WP Fastest Cache." With these changes, we were able to fully resolve the cache and display issue.
