I will manage the WordPress website by performing the following on a regular basis
1. Staging website setup if not exist (Hosting should have enough space and supports the same)
2. Plugin Upgrades (Free and Premium)
3. Theme Upgrades (Free and Premium)
4. WordPress Core Upgrades
Please Note:
For Premium theme upgrade the customer need to provide the uptodate theme
For Premium plugins upgrade the customer need to provide either the credentials to those websites or need to provide the updated plugins
