Title: Plugin ZIP Generated on Local Environment Causes Fatal Error on HTTPS Server Last modified: July 17, 2026 --- # Plugin ZIP Generated on Local Environment Causes Fatal Error on HTTPS Server * [Parth Dangar](https://wordpress.org/support/users/pdangar/) * (@pdangar) * [5 days, 11 hours ago](https://wordpress.org/support/topic/plugin-zip-generated-on-local-environment-causes-fatal-error-on-https-server/) * Hello, * I found an issue while using your Download Plugin plugin.Environment - **Local Environment:** Windows (WordPress local installation) - **Live Environment:** HTTPS server (Linux) * Issue Description * I installed the Download Plugin plugin on my local WordPress setup and used it to download plugins. I tested this with multiple plugins, including your own plugin. * After downloading the plugin ZIP from my local environment, I uploaded it directly to my live HTTPS server and tried to activate it. During activation, WordPress threw a fatal error. * I also noticed that the plugin directory structure was changed after uploading. Please refer to the attached screenshot showing the directory that was created after activation. * To verify the issue, I manually created a ZIP of the same plugin from my local environment (without using the Download Plugin plugin) and uploaded it to the same live server. In that case, the plugin activated and worked correctly.Possible Cause * It appears the ZIP generated by the Download Plugin plugin may be preserving Windows-style directory separators (`\`) instead of converting them to Unix/Linux directory separators (`/`). * Since my local environment uses backslashes (`\`) and the live Linux server expects forward slashes (`/`), I suspect this is causing the incorrect directory structure and resulting in the fatal error. * Could you please investigate this issue? I have attached a screenshot of the directory structure created after uploading the ZIP generated by your plugin. * **Reference Image**: [https://ibb.co/vCHFZXC8](https://ibb.co/vCHFZXC8) * Thank you. - This topic was modified 5 days, 6 hours ago by [Jan Dembowski](https://wordpress.org/support/users/jdembowski/).

We look forward to your response. * Thread Starter [Parth Dangar](https://wordpress.org/support/users/pdangar/) * (@pdangar) * [5 days, 6 hours ago](https://wordpress.org/support/topic/plugin-zip-generated-on-local-environment-causes-fatal-error-on-https-server/#post-18967972) * Thank you for your response. * Please find the requested information below: - **Local Environment:** LocalWP - **ZIP File:** Attached is the ZIP file generated using the Download Plugin plugin from my local environment. This ZIP is of your own plugin. - **Plugin Tested:** Download Plugin (your plugin) - **Plugin Versions Tested:** I tested with multiple versions of the plugin, including the latest available version, and experienced the same issue. * **Plugin file link**: [https://we.tl/t-Vizx6WchQmRURovx](https://we.tl/t-Vizx6WchQmRURovx) * Plugin Support [vincentpg](https://wordpress.org/support/users/vincentpg/) * (@vincentpg) * [5 days, 6 hours ago](https://wordpress.org/support/topic/plugin-zip-generated-on-local-environment-causes-fatal-error-on-https-server/#post-18967975) * Hi, * Thank you for sharing the additional information and the generated ZIP file. * We have received the details and are currently investigating the issue on our end. Our team will review the archive structure and attempt to reproduce the behavior using a similar environment. * We appreciate your detailed report and the effort you put into helping us diagnose the issue. We’ll keep you updated as soon as we have more information or findings to share. * Thank you for your patience.
