Add to Cart Not Working

Well, I did a search on Add to Cart and it told me that it is too common and I went through 10 pages.... Anyways, I have OC 3.0.3.2 and the add to cart button is not working with the default theme. Any ideas?

My guess would be a CORS issue.

What is CORS?

https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

you probably are mixing either urls with http and https or www and non-www or both.

Is having a mixed url that is supposed to be SEO friendly normal in 3.0.3.2? I am running another site on 2.0.3.2 and the urls are clean looking. Below is the one that I am having trouble with.

https://curtistacticalsuppressorsandrif ... ct_id=1921

And, my host provider supposedly inserted the code in the .htaccess file that should have resolved the CORS problem. Well, that's what they said. lol

Hello mate,
Please provide us site URL so that we can analyze the exact issue as the information given by you is not sufficient.

Thanks!!!

You'd better provide a link to your store with the issue. Otherwise it's just a guessing contest.

he already has and a long one it is.

It's not CORS but I think it would be your htaccess as you links are screwed up.
add to cart ajax call goes to ?route=...... instead of index.php?route=....

It actually goes right, but returns 302 (permanent redirect) error.

yep, goes from
POST https://curtistacticalsuppressorsandrif ... t/cart/add
to
GET https://curtistacticalsuppressorsandrif ... t/cart/add
temp redirect

still think its htaccess

and wrong cache headers

don't do this as it will cache for 1 week anything which is not otherwise specified like html in your case

Code: Select all

ExpiresDefault "access plus 1 week"

always set default expire is now

Code: Select all

ExpiresDefault A0

and then specify the specific types which should be cached longer

and don't do this as that is where your 302 redirects come from

Code: Select all

RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^index\.php$ "https\:\/\/curtistacticalsuppressorsandrifles\.com\/" [R=302,L]

and this

Code: Select all

#redirect to https without www
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,NE,R=301]

write it like this

Code: Select all

# force ssl for non-binaries
RewriteCond %{HTTPS} !=on
RewriteCond %{REQUEST_URI} !.*\.(ico|cur|mp3|webp|svg|ttf|eot|woff|woff2|gif|jpg|JPG|jpeg|JPEG|png)$
RewriteRule ^(.*)$ https://curtistacticalsuppressorsandrifles.com/$1 [R=301,L,NE]

# redirect any request having www to ssl without www
RewriteCond %{HTTP_HOST} ^www\.curtistacticalsuppressorsandrifles\.com [NC]
RewriteRule ^(.*)$ https://curtistacticalsuppressorsandrifles.com/$1 [L,R=301]

bottomline, don't blindly copy htaccess snipplets from the internet and expect them to work.

if you want index.php?route=common/home to go away just add this

Code: Select all

				} elseif ($data['route'] == 'common/home') {
					$url = '/';

just before this in catalog/controller/startup/seo_url.php

Code: Select all

				} elseif ($key == 'path') {
					$categories = explode('_', $value);

Thanks for the replies. I am not the htaccess expert, but I hope that I made the right changes in the right places. Not sure if I need to do anything at the end where I have it in bold.

move this

RewriteBase /

to right after

Code: Select all

RewriteEngine On

lose this:

Code: Select all

  <filesMatch "\.(x?html?|php)$">
    Header set Cache-Control "public, must-revalidate"
  </filesMatch>

add this

Code: Select all

AddOutputFilterByType DEFLATE application/json

after

Code: Select all

AddOutputFilterByType DEFLATE application/xhtml+xml

this

Code: Select all

ExpiresDefault "A0"

should be this

Code: Select all

ExpiresDefault A0

directly after

Code: Select all

ExpiresActive On

why is this still there?

Code: Select all

RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^index\.php$ "https\:\/\/curtistacticalsuppressorsandrifles\.com\/" [R=302,L]

lose it.

Well, that worked! I truly do appreciate your help and patience!!!

I just checked the URL issue and it is still putting in a non SEO friendly ending on when it comes to the products. It seems to be slightly better than it was... lol

check if product 1919 actually has seo keywords defined.
