Title: Bulk optimization issues – HTTP 301/ParseError & Internal error Service Unavail. Last modified: July 10, 2017 --- # Bulk optimization issues – HTTP 301/ParseError & Internal error Service Unavail. * Resolved [cookieandkate](https://wordpress.org/support/users/cookieandkate/) * (@cookieandkate) * [8 years, 11 months ago](https://wordpress.org/support/topic/bulk-optimization-issues-http-301parseerror-internal-error-service-unavail/) * Hi, I’m so glad I found this plugin! Thank you for developing it. I’m trying to optimize a large library (2.8GB, 38k total images including all image sizes— I have about six image sizes) but I’m receiving a LOT of errors. * At this point, I’m only getting about 5 images optimized before I receive and error. I can’t hit refresh that many times! * I’m wondering if this is an issue with my server, and if so, if I should wait to optimize my images until I switch to a new host soon, or if it’s an issue with your servers. * Here are the errors I’m seeing most often. * Latest error: Error while parsing response: No error (#0) (HTTP 301/ParseError) * Internal error Service Unavailable * Any guidance would be much appreciated! Also, for successfully completed images, why does it sometimes say 6 sizes optimized and 1 size compressed? Does compressed mean resized? * Thank you, Kathryne Viewing 3 replies - 1 through 3 (of 3 total) * Plugin Author [TinyPNG](https://wordpress.org/support/users/tinypng/) * (@tinypng) * [8 years, 11 months ago](https://wordpress.org/support/topic/bulk-optimization-issues-http-301parseerror-internal-error-service-unavail/#post-9308238) * Hi Kathryne, * Thank you for reaching out to us!
