Keeping your WordPress sites updated is one of the best ways to maintain compatibility, performance, and security.
With the Pressable MCP integration, you can use AI assistants like ChatGPT or Claude to quickly:
- Identify sites not yet on the latest WordPress version
- Upgrade eligible sites
- Check for post-upgrade PHP errors
- Review warnings and compatibility issues
- Roll back WordPress version if needed
This workflow is especially useful for agencies or customers managing multiple sites at once.
Before You Begin
Before updating WordPress core across multiple sites, we recommend:
- Updating plugins and themes first, then confirming the site functions normally before changing WordPress core versions
- Testing a few representative sites before bulk updates
- Reviewing any custom plugins, MU plugins, or bespoke code
If a site is disabled, it cannot be upgraded until it is re-enabled.
Step 1: Connect Pressable MCP
Connect your Pressable MCP integration to your AI assistant.
Once connected, the assistant can securely interact with your Pressable account to:
- Inventory sites
- Check versions
- Upgrade WordPress
- Review logs
- And much more!
Step 2: Inventory Your Sites
Ask the AI assistant to identify which sites are already on the latest WordPress and which still require updates.
Example prompt:
List my sites by WordPress version and identify any sites that cannot currently be upgraded.The assistant can also identify:
- Disabled sites
- Staging or sandbox environments
- Sites already on the latest WordPress version
- Sites requiring manual attention
Step 3: Test Representative Sites First
Before upgrading every site, test a few sites that represent your common configurations. If you plan to update plugins or themes, test those changes separately before testing WordPress core version changes.
For example:
- Sites using the same theme
- Sites using the same page builder
- WooCommerce sites
- Sites with custom plugins or MU plugins
If those updates complete successfully with minimal issues, the broader rollout is more likely to proceed smoothly.
Example prompt:
Upgrade any eligible live sites still on a previous WordPress version to the latest, then check PHP logs for warnings, parse errors, or fatal errors.Step 4: Review Logs After Updating
After upgrading, review PHP logs to identify any compatibility issues.
Common examples include:
- Deprecated warnings
- Undefined array key warnings
- Duplicate constant definitions
- Parse errors
- Fatal errors
Not all warnings are critical.
Typical Error Severity Guidelines
| Error Type | Severity | Recommended Action |
|---|---|---|
| Deprecated warnings | Low | Monitor and update plugins/themes |
| Undefined array keys | Low-Medium | Review compatibility |
| Duplicate constant warnings | Low | Usually safe temporarily |
| Parse errors | High | Immediate investigation recommended |
| Fatal errors | Critical | Roll back version |
| Chmod/Read-only filesystem warnings | Usually low | Review filesystem expectations |
If no significant errors appear after testing representative sites, you can proceed with broader updates more confidently.
Step 5: Roll Back if Necessary
If a critical issue occurs after upgrading, MCP can help identify the issues from log files, or roll back to the previous WordPress version.
Recommended workflow:
- Roll back the WordPress version on the affected site
- Confirm functionality
- Investigate the source of the issue
- Reattempt the update after resolving compatibility problems
Example prompt:
Roll back <sitename(s)> to WordPress <version number>When possible, test changes and troubleshooting steps on staging environments first.
Recommended Rollout Workflow
For larger environments, we recommend the following process:
- Update plugins and themes
- Identify sites not yet on the latest WordPress version
- Upgrade a few representative sites
- Review logs and validate functionality
- Upgrade remaining sites in batches
- Review logs again
- Roll back only sites with critical issues
While MCP can automate much of the upgrade workflow, customers should still validate site functionality after updates, especially on sites with custom code, WooCommerce functionality, or complex plugin stacks.
