Nope, it should only spin for a little while, and then start showing you a progress bar, very similar to the media library optimization.
Often times, specific files will cause some of the filetype/mimetype functions to spring a sudden memory leak, and that will cause it to get ‘stuck’. It’s a little bit tricky to troubleshoot, but here’s how to do it:
In the file ewww-image-optimizer.php, you should see this function at around line 978: ewww_image_optimizer_mimetype().
A couple lines into the function, you’ll see a debugging line that says something like “testing mimetype: $path”.
Directly below that line, add this:
ewww_image_optimizer_debug_log();
Then, turn on debugging and run the Scan & Optimize. Then, please post the last 25-50 lines of output from ewww-image-optimizer/debug.log (via pastebin if necessary).
nosilver4u – Thanks for your help. Here is the debug file:
http://pastebin.com/fiRYFnH1
Is that everything that was in the debug.log file, or was that from the settings page?
Yes, that was the entire debug.log file. I clicked “Scan & Optimize” and then let it run for 3-4 minutes and then copy/pasted the content from that file.
Should I clear out the debug file and run it again?
Yes please, you can just delete the file completely, it will get recreated when you run it again. And make sure you added the ‘ewww_image_optimizer_debug_log()’ function right under the line that says ‘testing mimetype…’ in common.php otherwise we won’t get any useful output. I suppose we still might not if the problem is somewhere else, but that’s our starting point.
Is the file to be edited ewww-image-optimizer.php or common.php?
sorry, I misspoke in that last post, it is ewww-image-optimizer.php
Cool, I will give it another shot. On a sidenote, have you heard of any issues with images not displaying after the optimizer is installed and ran? My site in Safari (iMac and iPhone) is not displaying thumbnails and slider images. Either the slider images show up and not the thumbnails (posts) or it’s the other way around. I checked Chrome/Safari and those browsers seems to be working fine.
I figured it out. Looks like it’s an issue with my caching plugin.
Glad you found the glitch, making a site fast and awesome can be a bit tricky at times, but if you stick with it, you can achieve some pretty impressive results.
Let me know what you get when you run the Scan & Optimize again.
Okay, I removed the debug file and ran it again. Here is the contents of the new debug file:
http://pastebin.com/RbVSQQf3
Here is the code from the “ewww-image-optimizer.php” file after making the changes:
function ewww_image_optimizer_mimetype($path, $case) {
global $ewww_debug;
$ewww_debug .= "<b>ewww_image_optimizer_mimetype()</b><br>";
$ewww_debug .= "testing mimetype: $path <br>";
ewww_image_optimizer_debug_log();
if ( $case == 'i' && preg_match( '/^RIFF.+WEBPVP8/', file_get_contents( $path, NULL, NULL, 0, 16 ) ) ) {
return 'image/webp';
Well, I think I was looking for the wrong culprit here. I think it might be another plugin interfering with the ajax responses. If you know your way around a javascript console (either the one in Chrome, Firefox, or even better the Firebug extension for Firefox), you can watch the ajax queries, and then expand them to see the responses.
Open the console, and then run the Scan & Optimize to see what happens, and what the response is. If you get stuck, send me a login via https://ewww.io/contact-us/ and I’ll take a look myself.
If you do find something (or even if you don’t and it all looks normal), a screenshot of the console output would be helpful.
Did you ever find out anything?
Sorry for the delay. Here is the output from the javascript console in chrome:
