Yesterday my site stopped returning first class parcel quotes from USPS. I did not add or subtract anything from my site in days. I am using 1.5.5e. I have the first class parcel box checked. All other shipping quotes are being received. I did debug USPS and the log looks like USPS returned the quote but at the bottom of the log it only shows that priority mail was shown to the customer. I restored my site to a previous backup. I uninstalled and reinstalled the USPS plugin. Nothing helped. Do you think this has anything to do with my web host? I know they have been experiencing problems because they are based in Houston TX. Unfortunately support service is down. I couldn't find any info that it might be USPS and I also have an ETSY shop that is giving correct quotes so I didn't think it was that. I have tried everything I can think of. Any suggestions????
