I have been having an issue with one of my clients. The thumbnails for this SIGPro don't display until I change how PHP is running. I switch it to fastCGI Application then back to Apache Module. After a day or so the thumbnails stop displaying again. I do the same method to fix it again.
There are no errors in the error_log file. Here is the source code that is generated when the thumbnails are not displaying:
<div class="article-content">
<p><strong><span style="color: #993300;">Colour samples are shown on oak and are as accurately reproduced as possible. Colours vary based on application technique, wood type and lighting conditions. Always test stains on spare pieces of the wood that you will be staining. Sample wood colour chips are available upon request.</span></strong></p>

Any help would be appreciated.
