Troubleshoot-Resolve 503 Error on my Website and make sure the database is connected and working fine (Quick fix)

Technical Status Report: Resource Exhaustion (503 Error)

Site: brutheenterprises.com Environment: A2 Hosting (Shared) | 2GB RAM Limit | 100% CPU Limit
1. The Issue

The site is currently experiencing a persistent 503 Service Unavailable error. Analysis of the A2 Resource Usage shows the account is hitting its Physical Memory (2GB) and CPU (100%) ceilings almost immediately upon server reset.

2. Actions I HAVE already taken

Plugin Isolation: Renamed the /plugins/ folder to plugins_hold.

Process Reset: Cycled PHP versions (8.3 to 8.2 and back) to kill hanging lsphp processes.

Caching: Flushed and Enabled LiteSpeed Web Cache via cPanel.

Security: Briefly disabled ModSecurity (site attempted to load but crashed again instantly).

Cron/XML-RPC: Added DISABLE_WP_CRON to wp-config.php and blocked xmlrpc.php via .htaccess.

Redundancy Check: Identified multiple backup (Updraft, WPvivid, Duplicator) and image optimization plugins (Converter for Media, Elementor Optimizer) that may be clashing.

3. Current Observation

Even with the plugins folder renamed, the RAM and CPU usage remain at 100%. This suggests the issue is either:

A resource-heavy Theme (TemplateMela/Wooti) causing a memory leak or infinite loop.
A Layer 7 / Brute Force attack (Bot hammering wp-login.php or index.php).
A corrupt .htaccess or server-side process loop.

4. Instructions for Developer to fix it unless it is something else.

a. Identify the specific PHP script causing the spike using top or the A2 "Snapshot" tool in Resource Usage.
b. Analyze the error_log for specific "Fatal Error: Out of Memory" or "Maximum Execution Time" traces.
c. Audit the Theme code (TemplateMela Core) for compatibility issues with the current PHP version.
d. Check Visitor Metrics to see if specific IPs need to be hard-blocked at the server level.
e. Clean up redundant plugins once the site is stable to stay within the 2GB RAM limit.

Thank you!
