WordPress Repair: Plugins, PHP Update

My WordPress site suddenly dropped its side-widgets, the layout broke, and I now run into the infamous white screen of death whenever I try to activate roughly a dozen plugins. Some of those plugins are non-negotiable because the theme depends on them, so I can’t simply wipe the slate clean.

Here’s what I need from you:

• Audit every installed plugin, pinpoint what’s clashing, and safely remove anything the site no longer relies on.
• Reactivate and stabilise the theme-required modules while keeping core tools such as the SEO, form builder, and security functionality intact.
• Bring the server up to the latest compatible PHP version and resolve any deprecation warnings that surface.
• Restore the original sidebar and overall styling so the front end looks polished and consistent across modern browsers.
• Deliver a brief hand-off report outlining what was fixed, which plugins remain active, and any follow-up maintenance recommendations.

The job is done when the site loads cleanly—no blank screens, no fatal errors—and every essential feature behaves exactly as expected.
