Leave HTTPS redirect off but enable HTTPS to lead to the same directory.
Rewriting a redirect is what is also causing an issue.
Please also don't forget this or problems will continue
You are missing the following folder which is generating all the theme CSS/JS issues. You will want to bring it over from your backup:
/uploads/css_built_3/
Your server is also misconfigured as when I turn HTTPS on, it is getting a 404 for everything. HTTPS and HTTP should be pointed to the same directory.
We asked you several times to remove this. Please keep it removed or we will not be able to assist further.
Unfortunately, now, PHP sessions are failing so we are unable to login
The link I posed above should be present on your server already, unless your server is misconfigured, it should be delivered. As mentioned, it does not get brought through the software, it is delivered directly from your server.
You would need to check the configuration differences then between the folder locations as something is off on the server configuration. Which is again, outside our scope of support.
For example, here is an image on your server and resulting in a 500 ISE: http://www.jeepforum.nl/uploads/monthly_2017_01/Jeepforumlogo2017.png.96033b321f9a82964eb45d0d642876f9.png
Unfortunately, that is server configuration beyond what the requirement checker checks for. We assume the basics of a web server and delivering images, javascript, and CSS can be done.
Unfortunately, it is not a software issue, as mentioned. CSS, Javascript, and images all load directly from your server and not through our software so would not be a software issue.
We do not. I run php-fpm on my own test server. You would need to simply configure your server correctly so it can deliver CSS/JS/images/etc...
The issue may be Litespeed TBH. People did have issues with that and we do not directly support it.
You would want to test disabling that and then try again.
If it still is an issue, please ensure that the forum has download permission for the member group.
Setting our software to a debug won't help because it is your server throwing the 500 ISE.
CSS is loaded directly from your server, not through our software.
You would need to contact a server administrator as we do not provide support for server environments/configurations. As the CSS/JS/Images are creating 500 Internal Server Errors, this is not a software error but a server error in rendering these files from your server. Starting with reviewing your server error log would be recommended but we can't really provide support for your server, only our software.
You would need to contact your hosting provider as simply accessing an image is rendering a 500 Internal Server Error after I cleared cache via the ACP. This would be a server issue and need to be addressed by them.
We would need to look further into this for you, however the access details on file appear to be incorrect or missing. Could you please update these details by visiting your client area, selecting the relevant purchase, then clicking "Review/Update Access Information" under the "Stored Access Information" section.
We look forward to further assisting you.
Unfortunately, there isn't really a way to have stock recorded and have it be visible in the store but not purchasable. It's really one or the other currently.
