Problem: Plesk MySQL requires password authentication
User report: "ERROR 1045 (28000): Access denied for user 'root'@'localhost'"
Result: 0 databases detected on Plesk servers
Root Cause:
Plesk stores MySQL admin password in /etc/psa/.psa.shadow
All MySQL queries were using passwordless 'mysql' command
This works on cPanel (uses ~/.my.cnf) but fails on Plesk
Solution: build_databases_section() in lib/reference-db.sh
1. Check if running on Plesk and /etc/psa/.psa.shadow exists
2. Read admin password from file
3. Build mysql_cmd variable with credentials
4. Use $mysql_cmd for all database queries
Changes (lib/reference-db.sh):
Lines 161-166: Added Plesk credential detection
Line 168: Use $mysql_cmd for SHOW DATABASES
Line 179: Use $mysql_cmd for size calculation
Line 184: Use $mysql_cmd for table count
Impact:
✅ Database discovery now works on Plesk
✅ Backwards compatible with cPanel/InterWorx/Standalone
✅ No performance impact (password read once)
Status: Ready for testing on Plesk server
