Website Crashes and Poor Performance on PageSpeed Insights

Firstly, I’m experiencing frequent crashes with the “Aw, Snap!” error message, causing disruptions for visitors. I’ve tried various troubleshooting steps, but the problem persists. I kindly request your guidance in identifying the cause and finding a solution to prevent these crashes.

Secondly, my website’s performance score on PageSpeed Insights for mobile devices is only 29/100. I understand the significance of a fast and optimized website for user experience. Could you please provide me with recommendations and solutions to improve the loading speed and overall performance based on the audit report?
