WordPress Elementor 400 Error Fix

Job ID: 40208723

Budget: ₹600 – ₹1,500 INR

I run a WordPress site hosted on Bigrock and build all of my pages with the free version of Elementor. Out of nowhere, Elementor now greets me with a “400 Bad Request” message, and every action that should write to the database—contact-form submissions, publishing or updating blog posts, and the wallet-deduction routine tied to WooCommerce—silently fails.

Nothing was recently updated in core, themes, or plugins, so the issue looks server-side or the result of a conflict that crept in unnoticed. I need the site back to full working order and the root cause documented so the same error doesn’t return.

Acceptance criteria
• Elementor editor loads without 400 errors on every page.
• Contact-form submissions are processed and stored/emailed as expected.
• Blog posts save, update, and publish normally.
• Wallet-deduction logic completes successfully and logs the transaction.
• A brief report outlines what you found, what you changed, and any preventive steps I should take.

You’ll have full WP admin and cPanel access, plus SSH if required. Please feel free to suggest any server-level tweaks, plugin removals, or .htaccess adjustments—whatever reliably solves the problem without breaking existing design or data.
