htaccess rule not working without R=301 flag? - .htaccess

My quest to understand htaccess continues. I haven't read anything useful in the documentation for this problem. This is my .htaccess:
RewriteEngine On
RewriteBase /
# e.g. Rewrite 'contact' to 'index.php/main/lessons'
RewriteRule ^contact$ index.php/main/lessons
The rule does not work, it is as if the rewrite doesn't even take place. The url is unchanged as just get a blank page. I want to redirect any request to /contact to /index.php/main/contact. However, when I add the [R=301] flag,
it works. I see the permanent redirect request in chrome developer tools and I end up at the right page. Any help?
Thanks.
This is what I get from my error log with LogLevel alert rewrite:trace3 in my httpd.conf:

I should also note that I am using CodeIgniter.


Using code igniter you can just define redirections in "application/config/routes.php"
Just add this line:
$route['contact'] = 'main/contact';

To force use python3.9 after install libapache2-mod-wsgi-py3 django

I installed libapache2-mod-wsgi-py3 but It seems good for python3.6. My problem is set mod-wsgi for use python3.9 because my app django has all modules installed for this version.

htaccess rewrite slow... better way of doing this?

I need to sort out my htaccess rules as i think this is the cause for many slow requests...
I have done the following that works but not sure if theres a better and efficient way other than the way i am doing it right now...
i cant really change the structure before, so i have to do this way and change the way i structure it better in future .
I wanted it dynamic, without having to change the existing URLs, that alot of people are aware of and indexed already ages ago... Also, i dont want to permanently redirect....
My file structure, (all in the same folder)
# If requested resource exists as a file or directory go to it
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule (.*) - [L]
RewriteRule ^sitemap\.xml$ /sitemap.php [L]
# i dynamically change the page to AMP if /amp/pagename.php is accessed....
RewriteRule ^amp/(.*) /$1 [NC,QSA,L]
#i have added this one rule again as the amp page for the home page is just /amp and the rule above with the trailing slash, didnt execute...
RewriteRule ^amp(.*) /$1 [NC,QSA,L]
RewriteRule ^car-price-(.*)-([0-9]+).php$ _car-price-mn-yr.php?gpimnt=$1&gpiyr=$2 [QSA,L]
#car-price-january-2018.php <- multiple urls: all months, years from 2009 to now...
RewriteRule ^car-price-([0-9]+).php$ _car-price-yr.php?gpiyr=$1 [QSA,L]
#car-price-2009.php <- yearly summary, many urls: 2009 till now.
RewriteRule ^car-price-([A-Za-z-]+).php$ _car-price-wildcard.php?_gpwilcvar=$1 [NC,QSA,L]
#car-price-london.php <- similar to the above, making it confusing.... many cities...car-price-scotland.php etc
RewriteRule ^car-price-([\w-]+).php$ _car-price-wildcard.php?_gpwilcvar=$1 [NC,QSA,L]
#gbp-rate-today-usa.php <- i have different urls for e.g. cad.rate-today-usa.php, etc...
RewriteRule ^([\w-]+).php$ _car-price-wildcard.php?_gpwilcvar=$1 [NC,QSA,L]
#why-do-diesel-cars-cost-more.php <-i have many articles that does not have a prefix or some sort to make this easier..
these rules are making my website 4 seconds longer to load.... is there a better set of rules which can help, or is this the only way?

Combine the /amp rules:
RewriteRule ^amp(/.+)? /$1 [NC,QSA,L]
As a general rule of thumb, avoid using the .* matching, as the * is greedy and creates a larger backtracking.
Next, instead of having separate PHP scripts accepting the optional gpimnt parameter, you can do this in a single PHP file. If the value for the same is not present, proceed with only the gpiyr value received. This can again be combined with conditional gpwilcvar parameter etc. and reducing the total number of patterns your URL will be matched against. A single defined() (or isset()) call inside PHP is faster than pattern matching.

.htaccess RewriteRule hates "Portfolio" word

so this is my .htaccess:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
Now, domain.com/About is calling to file About.php just fine same as domain.com/portfolio works with portfolio.php.
Problem - domain.com/Portfolio does not work with Potfolio.php, error:
/Portfolio/.php was not found on this server.
I have no idea why it does this just with this one particular word, it gives headache already. Any ideas?
PS. There is no Portfolio folder
Update: error.log

uWSGI suddenly won't start again after server crash on Debian

After my server crashed i am unable to start uWSGI again, and keep getting following errors on unlink() and bind().
I start my service as root, so it makes it even more strange.

pidfile2 = /var/www/servers/example/production/logs/example.pid

Albeit you run the server as root it drops privileges to 33 (presumibly www-data). This user (33) must own the right to remove /var/www/servers/example/production/sockets/example.sock.
Probably the crash corrupted the inode that now has wrong attributes. Fix them and it should work again.
