OpenCart 4.x Multivendor Extension: Page Not Found Troubleshooting

Introduction: Embarking on the journey of enhancing your OpenCart 4.x store with the Purpletree Multivendor Extension can be an exciting step towards expanding your e-commerce capabilities. However, users often encounter a common stumbling block during installation - the dreaded "Permission Denied" error. Fear not! This guide is here to help you seamlessly navigate and overcome this challenge.

Unveiling the Culprit: Naming Conventions Matter!

One of the key reasons behind the "Page not found" or "permission Denied" error is often overlooked – the file naming convention.

The extension package must be named precisely only as "purpletree_multivendor.ocmod" for OpenCart 4. x compatibility not others like purpletree-multivendor-oc-2.x.ocmod or purpletree-multivendor-oc-4.x.ocmod.

Unfortunately, the downloadable package may not adhere to this specific naming convention, leading to frustration among users.

Understanding the Quirk: Purpletree Multivendor Naming Issue

Acknowledging the issue is the first step towards a solution. The Purpletree Multivendor Extension may be packaged with a different filename, causing a mismatch with OpenCart 4.x expectations. The recommended filename is crucial - it should be "purpletree_multivendor.ocmod," and deviations from this can result in the elusive "Permission Denied" message.

The Fix: Embrace the Purpletree Multivendor.ocmod Magic!

To resolve this hiccup, follow these steps:

  1. Identify the Culprit:

    • Check the downloaded extension package and ensure its filename adheres to the correct convention.
    • If the file is named differently, don't panic; you're not alone!
  2. Rename to Reignite:

    • Embrace the power of renaming! Change the filename to "purpletree_multivendor.ocmod" before proceeding with the installation.
    • Be cautious not to retain any previous version-specific tags like "oc-2.x" in the filename.
  3. Installation Bliss:

    • Once the filename aligns with the prescribed convention, attempt the installation again.
    • Voila! The "Permission Denied" roadblock should vanish, allowing you to proceed with the Purpletree Multivendor Extension installation on OpenCart 4.x.
