Performance and Server Errors

Database latency

If many authenticated pages become slow at the same time, check MySQL/MariaDB latency, locks and hosting resource limits.

External services

SMTP, IMAP and licensing involve network services. Check provider/network health when only those actions are slow.

Module actions

A module enable/install can perform migrations and dependency checks. Repeated 40–50 second delays are not normal; inspect the PHP/server log and database performance.

PHP error log

Use the hosting PHP error log for blank pages or unexpected server errors.

Browser symptoms

A page that keeps buffering after login is not necessarily an authentication problem. Check the server request/database/network work performed by the destination page.

Avoid random fixes

Do not repeatedly change session/login code when the delay affects unrelated menu pages. Identify the slow operation first.
