My WordPress site sits on a shared-hosting plan and, despite its light traffic, it frequently maxes out resources. It's completely down at the moment. Getting a "504 Gateway Time-out - nginx/1.23.4" error. And my emails, Im able to login fine and send outgoing email fine, it arrives to the recipient instantly.....BUT.....incoming mail takes 5-7 hours to appear. So an email I'm supposed to receive at 1PM, shows up hours later at 7pm. All core, theme and plugin versions are already up-to-date, so the slowdown clearly lies elsewhere. I need someone to: • trace what is overloading the server (cron loops, poorly coded plugin, database bloat, SMTP bottleneck, etc.) • tune WordPress, MySQL, PHP-FPM and the mail route so page loads return to normal and emails land within minutes, not hours • give me a concise, plain-English hand-over explaining what you changed and, if the shared environment proves inadequate, recommend the right VPS specs and migration steps Please bring experience with typical optimisation tools—Query Monitor, WP-CLI, object caching (Redis/Memcached), SMTP plugins, server logs—and a track record of cutting load times and fixing delayed mail on shared hosts. I am ready to grant cPanel, WordPress admin and webmail access as soon as we agree on the plan.
