Help for people running wordpress

[MattWilcox]

Having trouble with your Wordpress install? Please comment here.

Remember that any problems are very likely to be something with your server configuration or Wordpress set up. As those things can be so varied, please can you give as much info as possible about them "it doesn't work" isn't enough for anyone to help you :)

Are you running WP on a domain or in a sub-folder of a domain? Are you running any plugins or themes that may be making use of a .htaccess file? What server and software versions are you running? etc. Everything you think might be relevant. Thanks.

Hi. I'm trying to get it to work on my Wordpress site, but don't know exactly how. I've installed WP in a subfolder wcms. Right now i have all the stuff in the root: .htaccess, adaptive-images.php and ai-cache folder with permission 777. htaccess file looks like that->

RewriteEngine On
RewriteCond %{REQUEST_URI} !images
RewriteCond %{REQUEST_URI} !uploads
RewriteRule .(?:jpe?g|gif|png)$ adaptive-images.php

RewriteBase /wcms/
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wcms/index.php [L]

Should i put the php file and cache folder in a subfolder where the WP is installed (wcms) or even in my theme folder? The .htaccess file must be in the root? If i put a-i.php and cache folder in wcms folder or theme folder, what files and what paths i have to change? I've tried different options but could not get it right. In some cases all my images where missing. That seems to be the question of these lines in htaccess: RewriteCond %{REQUEST_URI} !uploads. Am i right? At the moment i see all my images but checking the site on my phone still gets large file (900x650px).

I don't know myself as I don't use WordPress. I do think that the RewriteBase statement may be causing problems for you though.

The .htaccess file needs to be at the highest level you'll want to use AI with, which is normally root, but you may be ok with it in the /wcms/ folder instead, so give that a try if you like. I don't actually know what rewrite base does (I can guess, but wouldn't know how it might effect other things). It's almost definitely messing about with paths though, and that is likely why it's not working for you.

I have the same setup as Kaimps:

Wordpress installation in sub-folder, ai-cache folder, adaptive-images.php and htaccess also in subfolder.
Wordpress still runs from that sub-folder (I have not moved the index.php file and changed the path to
the installation yet, only when going live).

As soon as I add the htaccess statement I get an "Internal Server Error" (blank page with that message),
this statement seems to be causing the issue:

RewriteRule \.(?:jpe?g|gif|png)$ adaptive-images.php

This is how my whole .htaccess file looks like:

`
RewriteEngine On
RewriteBase /site/
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /site/index.php [L]

RewriteCond %{REQUEST_URI} !themes
RewriteRule .(?:jpe?g|gif|png)$ adaptive-images.php
`

I also removed the Wordpress rewrite statement i.e. RewriteBase for testing, but the result is the same,
whenever I add the following I get an internal server error:

RewriteRule \.(?:jpe?g|gif|png)$ adaptive-images.php

Any hints greatly appreciated, it would totally solve the whole dilemma around image for responsive websites (based on Wordpress)!

Might best be solved as a plug-in in wp.org, this way it's handled once for the WP crowd.

[MattWilcox]

It likely would, only I don't use WordPress so can't make one. Anyone's welcome to do so if they have the skills! :)

I just installed the script on a subfolder installation of wordpress. Here is what I did that worked....

The .htaccess and the adpative-images.php file are both in the subfolder, the Wordpress installation root.

I created a new folder in wp-content/uploads for the stored images and added the path to the adaptive-images.php file: "wp-content/uploads/adaptcache".

I then edited the .htaccess file to restrict access to my theme files, plugin files, wp-admim folder and wp-includes folder.

RewriteCond %{REQUEST_URI} !wp-content/themes
RewriteCond %{REQUEST_URI} !wp-content/plugins
RewriteCond %{REQUEST_URI} !wp-content/plugins
RewriteCond %{REQUEST_URI} !wp-includes
RewriteCond %{REQUEST_URI} !wp-admin

Hope this helps someone!

Anyone have any suggestions for integrating this script into a multisite Wordpress environment? I'm going to tackle it but thought I would throw the idea out for suggestions first.

[noeltock]

I did create a WP plugin for this, but not using the adaptive images code (certainly not for any negative reason, just envisioned a different fit/implementation): http://wordpress.org/extend/plugins/hammy/

[soulreverie]

nice... I'll take a look.
I appreciate the response... no need to reinvent the wheel if you don't have to!

[thetrickster]

Does anyone have any experience using this script in a Wordpress environment where the root is read-only? This means that our images are being processed using the WP-Read-Only plugin (http://wordpress.org/extend/plugins/wpro/) using Amazon's S3 buckets to store our images. Does this plugin work on images at external URLs? Does it require a cache folder to be writable on the server? I'm currently hosting the Wordpress site on Heroku with a custom PHP buildpack and Heroku Postgres as the database. I'd love to be able to use this for a new responsive site but I'm not sure if it works on images hosted on S3.

I think to remember that it does not work with remote images...

If AI is not working, you must ensure that .htaccess is not being altered by another .htaccess inside a child folder on your installation (in my case was a .htaccess inside wordpress folder)

I got it working fine in a sub-directory. Since I am running a multi-site installation, I put the files in /wp-content/blogs.dir/# (where # is the upload directory for my site), made the necessary changes to the paths in the files, and kabang! it worked like a charm.

Has anybody had any conflicts with running ai.php and W3 Total Cache?

[seezee]

Since my post 2 months ago, I've finally started using a smartphone -- ai.php no longer seems to work (not seeing any cache directories being created when I visit the site on the phone). I do have W3TC enabled on the network; it could be part of the problem?
