[galaxy-user] Unable to load FASTA files?

Is anyone else having trouble uploading FASTA files to the Galaxy server? I thought it was my files at first, but I have since tried to upload other FASTA files that I have previously had no trouble uploading and I get the same error reported in the info section when I click on the pen icon: Unable to queue job for execution. Resubmitting the job may succeed. (Unfortunately re-submitting the job does not succeed!). The file is 50 MB in size. Any help is greatly appreciated as I am unable to progress my work until this problem is corrected.
