jpegtran : Update available

Yes it works : I have the result ‘-rwxr-xr-x’. But the plugin always says “jpegtran : Update available” and I always have version 8b 16-May-2010 … Why ?

I cannot seem to get the update to work. Any ideas?
Otherwise I think it is working for JPEGs, right?

Yes, it is working. If all you are concerned about is JPGs, you should be just fine. It’s entirely possible that your webhost has disabled the ability to run executables in your web folder. You may want to ask them that, it would be useful for me to know if webhosts are doing that on purpose.

polkade, what do you get when you run this:

/homepages/35/d279464009/htdocs/wp-content/ewww/jpegtran-custom -v

also, then try this:
whereis jpegtran

which should tell you where 1and1 has installed jpegtran, then put that path in this command:
ldd /path/to/jpegtran

on my system, that would look like this, but yours may be different:
ldd /usr/bin/jpegtran
