Title: HTTP Error Last modified: August 30, 2016 --- # HTTP Error * Resolved [JordanC26](https://wordpress.org/support/users/jordanc26/) * (@jordanc26) * [10 years, 5 months ago](https://wordpress.org/support/topic/http-error-81/) * Hi, * For some reason even with Imagick installed, every time I upload PDF wordpress shows a “HTTP Error” message. Folder permissions are fine also. * The file uploads fine, but it does not create an image/thumbnail whilst this plugin is active. When disabled the file uploads as normal, no image and no error. * [http://www.highwaysindustry.com/phpinfo.php](http://www.highwaysindustry.com/phpinfo.php) * I can provide access if you can contact me?

From the phpinfo you posted it looks like ImageMagick is installed with PDF support so I don’t see any apparent reasons for why you should have problems with the plugin. * Generating the thumbnails requires some compute power, maybe you could try to upload some smaller PDFs to see if there is an improvement? * [nvkc](https://wordpress.org/support/users/nvkc/) * (@nvkc) * [10 years, 5 months ago](https://wordpress.org/support/topic/http-error-81/#post-6689769) * Same issue here.

I’m trying to use the plugin in localhost (xampp). When I try to upload a PDF file in a post, i get the “HTTP error”.

Can you send me the PDF-file for testing?
