Weird Wordpress Media Library image preview problem

Posted on 2016-10-02
Last Modified: 2016-10-11
For starters I moved the site from one server to another like I have done many times before but this is the first time I have seen this problem.

When I go to upload pics in the media library is seems to work fine:

After uploading
But when I go to refresh the page I get this:

After Refresh
If I go to the attachment details it also does not display the picture BUT the path does work and will display the picture in a browser.

Image Details
So really everything works except the preview which kinda makes things a pain in the butt to work with.

Any ideas? Thanks in advance for your help.

Have you tried using the dev tools in your browser to "inspect" the elements having the problem? This will probably help you find some more information on why it's happening.

Which browser are you using? In Firefox or Chrome, hit F12 to open the dev tools then, right click on one of the image's that's not loading, and choose Inspect or Inspect Element.

Hopefully that will give you the URL of the image that it's trying to load.

I tried that but Wordpress is replacing the image for the thumbnail review with this:

and not even going to:

where are the files are. In fact, not that I look, Wordpress is not even generating thumbnails anymore for me.

I think your PHP installation may be missing the php-gd package.

If you install the plugin "WordPress phpinfo" to your site, activate it, and go to Settings > WordPress phpinfo, then it should have something like included in the output:

Configure Command	'./configure' '--disable-fileinfo' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-gd-native-ttf' '--enable-libxml' '--enable-mbstring' '--enable-pdo=shared' '--enable-soap' '--enable-sockets' '--enable-zip' '--prefix=/usr/local' '--with-curl=/opt/curlssl/' '--with-freetype-dir=/usr' '--with-gd' '--with-gettext' '--with-imap=/opt/php_with_imap_client/' '--with-imap-ssl=/usr' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libdir=lib64' '--with-libxml-dir=/opt/xml2' '--with-libxml-dir=/opt/xml2/' '--with-mcrypt=/opt/libmcrypt/' '--with-mysql' '--with-mysqli' '--with-openssl=/usr' '--with-openssl-dir=/usr' '--with-pcre-regex=/opt/pcre' '--with-pdo-mysql=shared' '--with-pdo-sqlite=shared' '--with-pic' '--with-png-dir=/usr' '--with-xpm-dir=/usr' '--with-zlib' '--with-zlib-dir=/usr' '--with-litespeed'

Open in new window

See how the option --with-gd is included. If yours is missing that option, then you need to figure out how to add it, whether it be by contacting the hosting company, or by enabling the option yourself on your own server.

Two more things to consider:

When I upload an image the blue bar moves to 100% then it disappears. I get an HTTP error at the bottom of the page. I then refresh the page and I get the generic image placeholder like shown above.

The image does get uploaded
The link created by Wordpress does work if I manually go to it.
The image does not get duplicated and resized for thumbnails and medium size pics.
This is actually happening on the two sites I have moved over from GoDaddy VPS to InMotion VPS.
This is not happening on websites that were originally created on the new server.
I have tried using the default 2015 template vs the DIVI I am using but it still does not work.

It has something to do with the transfer of the site from one VPS to another.
