Request for Quotation (RFQ) for Website Bug Fix

Description

We are an online platform that hosts a multi-vendor marketplace. We are seeking a qualified developer or agency to diagnose and fix a technical issue currently affecting our website. This RFQ outlines the details of the issue and our requirements for resolution.______________
Issue DescriptionObserved Behaviour:
Store vendors are logged out at random intervals whilst editing the contents of their shops (adding or removing products), with no front-facing errors shown. Admin and customer users are unaffected. Seems to happen more often on Chrome compared to Edge.
Expected Behaviour:Store vendors should be able to add and remove products, and navigate the backend of the website, without being logged out.
Steps to Reproduce:1. Navigate to the dashboard for a store vendor (whilst logged in as DemoVendor)2. Add products, remove products and generally navigate. 3. You will be logged out without warning at some point. Sometimes instantly, other times it won’t happen for a long time.
Impact:This issue affects all store vendors, leading to reduced management of shops and reduced interaction with the platform. ______________
