Questions[permalinks](server)

Hello I used the wordpress one click deploy on google cloud and am trying to get custom permalinks working but every setting besides the default gives me a 502 server error.

My load balancer is setup with this frontend IP, 35.241.50.51
My backend IP is 34.69.91.228

My domain, hexcards.io, is set to the google name servers and I have a zone in the cloud dns which is pointing to the load balancer frontend IP, 35.241.50.51

Google gave me an SSL certificate and it is working fine with the load balancer.

In wordpress my site address and wordpress address are both set to, https://hexcards.io

Basically everything works fine until I try to switch permalinks which then gives me a 502 server error even in the wordpress admin.

• Can Wordpress permalinks work with a load balancer?
• How do I view 502 server errors with google cloud? It's apache 2.0+
• Is there a website where I can hire a google cloud & wordpress expert to help me?

EDIT:

I didn't configure apache, it was setup automatically with the wordpress one click deploy that google cloud has. I checked the apache2.conf file and there is no virtualhost directive.

Apache/2.4.38 (Debian) PHP 7.4.24 (cli) Wordpress is up to date

I've inherited a legacy PHP site running on Apache with a custom CMS. The URL structure is currently: https://example.com/topic.php?id=100&Title=Blog+Post+Topic

Is there an easy(-ish) way to automatically map that URL to a more friendly URL using an Apache rewrite so that the URL is like: https://example.com/blog-post-topic/

It reminds me of how WordPress permalinks map its /?p=100 style URLs to /blog-post-topic/

Any and all help is certainly appreciated. Thanks for reading.

• OS: Ubuntu 18.04.5 LTS (having my own VPS)
• WebServer: Nginx/1.18.0
• MySQL: mysql Ver 8.0.22 for Linux on x86_64 (MySQL Community Server - GPL)
• WordPress: 5.6

When I change the Permalinks option in WordPress (ScreenShot: /wp-admin/options-permalink.php) from the default (?p=123) to /%postname%/ (the last option on the page) I get the following error: "ERR_TOO_MANY_REDIRECTS" with status code 301 only for the Homepage (so directly example.com), all other pages working perfect, even the new permalink option is working right such that the default blog is accessible by: /hello-world/ directly.

Any idea why? This was the last thing to do such that my Server was finished, spent more time on this small bug than everything else lol. Note: I have disabled every plugin and except nginx cache which I use to clear the server-side caching. Also I visit the website incognito.

I followed this tutorial: SpinUp WP (I did everything till and including CH6). Hereby my NGINX Settings:

I have Wordpress installed in the root directory and configured properly using permalinks.

Alongside the Wordpress blog, I have a full-fledged custom developed php application with several pages. I want to not show the .php extension for any of the custom pages, but I'm now getting 404 errors for all the custom php pages.

http://url/blog-title-here (word press page - works)

http://url/register (custom php page - results in 404)

Here's what my .htaccess looks like:

# BEGIN WordPress 
<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteBase / 
RewriteRule ^index\.php$ - [L] 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L] 
</IfModule>

And here's what I have in httpd.conf

<Directory />
Options FollowSymLinks
AllowOverride All
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) $1.php [L]
</Directory>

I've been tasked with modifying an existing Wordpress site with URL rewriting. Problem is I've never done this before. I know these rules should go in a .htaccess file in root with something like this in it:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

However, I have no clue as to how I should specify the rules and conditions for rewriting. I've tried to read up on the mod_rewrite guide, but my somewhat lacking technical abilities limits my comprehension.

Here are the URLs that need rewriting and the desired results:

Generic blog post URL
www.example.com/?p=X
= www.example.com/blog/custom-post-title/

Specific pages
www.example.com/?page_id=2
= www.example.com/about/

www.example.com/?page_id=4
= www.example.com/bloggers/

www.example.com/?page_id=10
= www.example.com/results/

Generic blogger profile
www.example.com/?author=X
= www.example.com/blogger/author-name/

Any help with this would be greatly appreciated. Thanks in advance!
