I have a WordPress web site which is hosted on a distributed infrastructure. I have a web server(apache) and a cache server (varnish). When I load the site directly from web server everything is OK, but when I load the site from the cache, I sometimes get the following error:
Timthumb isn't displaying any images.
"A TimThumb error has occured
I saw some answers about this problem which mainly point out to the file permissions. But I don’t get any error related to permissions!! any help is appreciated.
