WordPress
Choose Post name permalinks so wiki, Markdown and REST routes work. Select a city timezone, for example Istanbul. Purge caches after updates.
WP-Cron handles backups, queued mail and reports. Low-traffic sites may need a hosting cron calling https://example.com/wp-cron.php?doing_wp_cron every five minutes. Disable WordPress’s visitor-triggered cron only after confirming the hosting job works.
System Check
With Flux Speed installed, System Check gathers PHP, extension, permalink, cron, mail, AI and package checks. Each error includes the action to take.
Troubleshooting
- White screen or HTTP 500: check
wp-content/debug.logand conflicting old plugins. - Interrupted wizard: reopen it to install remaining packages.
- Wiki 404: save Settings → Permalinks.
- Mail not sent: check Flux Mail SMTP settings and daily sending limits.
- Missing update: verify the release workflow, refresh server packages and clear cache.
