If you’re trying to access your website, but instead it downloads instead of loading in the browser, the issue is caused by the GZIP compression being enabled twice.
GZIP is enabled by default on GridPane servers, however, some plugins have an option to enable GZIP as well. If a plugin doesn’t check the server’s GZIP compression status and compresses the files anyway, it results in a doubled up compression. In this state, the file isn’t readable by the browser and instead downloads it as a blob.
We haven’t many cases of this issue, and so far I’m only aware of the WP Rocket plugin being the cause. You can deactivate this setting inside the plugin, clear your cache, and then the website should load correctly again on Nginx.
On OpenLiteSpeed, you may also need to remove any added setting to the
.htaccess file. WP Rocket and other plugins should remove this once the setting is disabled, but if you find that your site still downloads even after clearing the cache, you’ll need to check and fix this.
The .htaccess Location
.htaccess file is a hidden file located inside your websites /htdocs directory.
To view it, you’ll first need to connect to your server. If this is your first time doing so, please see the following guides to get started:
Editing Your .htaccess File
You can edit the file within nano with the following command (replace site.url with your website URL):
Clear out the configuration the plugin has added, and then you can save the file with CTRL+O followed by Enter. You can then exit nano with CTRL+X.
Now regenerate your vhost with (again replacing site.url with your website’s URL):
gpols site site.url
Clear your site’s cache and check the page again. Your site should now load correctly.
