We have put a lot of work into it, and it makes me happy to hear that our hard work has made an impression. With that in mind, it seems that the example link has gone inactive. In my past experience, most of the QR code problems seem to be a server side permissions related issue. Sometimes the server is not allowed to talk back to itself, which can cause the PDF library we use to not fetch the images properly. Other times, the file permissions of the cache dir for the qrcode lib are not correct. In rare other cases, it has been a plugin setting or conflicting plugin. Usually the other image issue either have the same permission issue, or they are simply not setup in their respective posts as the ticket expects them to be. * Without temporary access to a test area for your site, it is hard to say exactly what is causing the problem; however, here are the first steps I would take usually when troubleshooting this type of problem: * QR Image: – make sure that your file permissions in /wp-content/plugins/opentickets- community-edition/libs/phpqrcode/cache/ are at least as open as your uploads directory, and that the files are owned by the user that apache (assuming you are using apache) is running as. on many servers, this means that the files must be owned by ‘nobody.nobody’ (depending on implementation) and must have 755 permissions at least. – if the permissions are correct, double check that your sysadmin has not blocked request on the ‘loopback’ (ip address 127.0.0.1) for your server. somewhere along the line, some unwitting sysadmin started propagating that having that open was a security risk, so everyone started to hop on the band wagon. unfortunately that is misguided at best and actually causes more problems than it solves. just make sure it is open – if those dont leave a mark, then we may stuck until temporary access is provided. * Other Images: – first, even though it sounds like a dumb ‘duh i did that already’ idea, double check that the ticket product, the venue and the event all have their respective images. it only takes like a minute to double check, so you may as well – if that does not work, then double check that your uploads directory permissions are correct. the easiest way to check this quickly is to use the media library and upload a new image. if you get an error, then there is probably a permission problem. try resolving that like above under QR codes. – if that is still not making a change, then we may stuck until we can route around and help track the problem. * Hope this helps, Loushou * Plugin Author [quadshot](https://wordpress.org/support/users/quadshot/) * (@quadshot) * [11 years, 1 month ago](https://wordpress.org/support/topic/qr-code-not-on-pdf/#post-5776383) * This issue appears to be solved and was last updated a week ago. * @ibaan please let us know if you have other issues. * Thread Starter Anonymous User 7903281 * (@anonymized-7903281) * [11 years, 1 month ago](https://wordpress.org/support/topic/qr-code-not-on-pdf/#post-5776384) * sorry I didn;t have time to check yet… I’ll let you know asap! * [backbeatjohn](https://wordpress.org/support/users/backbeatjohn/) * (@backbeatjohn) * [11 years, 1 month ago](https://wordpress.org/support/topic/qr-code-not-on-pdf/#post-5776388) * Hello, I have installed the latest version of the plugin. Before I would post here, I read the previous advice and wrote to my ISP about the QR not generating or showing up on the tickets. The following is the answer. Everything is good at the ISP. Could the fact that we have not gone live with the domain be a contributing problem? The site is under an IP address right now. Everything else works with this terrific plugin. * I deactivated all unnecessary plugins and that didn’t work either. * I was wondering if you could maybe give me a hint on what else I can do or if you think this will clear up when using a domain name instead of an IP address? * Thank so much * John * ____________________________________________________________________ Hello John, * Thank you for contacting our Help Desk. * I’ve checked and confirm that the directory in question is set with the correct permissions and ownership.

Lets continue the conversation [over there](https://wordpress.org/support/topic/qr-not-generating-isp-verifies-all-good-on-server). * Plugin Author [loushou](https://wordpress.org/support/users/loushou/) * (@loushou) * [11 years, 1 month ago](https://wordpress.org/support/topic/qr-code-not-on-pdf/#post-5776404) * For posterity’s sake, we found that the pdf library we use, DOMPDF, initially required that the ‘allow_url_fopen’ php directive be set to ‘On’ in the php.ini file (research is documented here [https://wordpress.org/support/topic/qr-codes-not-showing-up-anywhere?replies=18](https://wordpress.org/support/topic/qr-codes-not-showing-up-anywhere?replies=18)). We wound up writing a solution that prefers cURL first, then the fopen method, since this seems to work better for most people. If you are having issues, try either installing cURL, or turning on allow_url_fopen. * Loushou * [Arciel](https://wordpress.org/support/users/arciel/) * (@arciel) * [11 years ago](https://wordpress.org/support/topic/qr-code-not-on-pdf/#post-5776406) * Hi. I already change the allow_url_fopen on php.ini to 1 by=ut qr code is not showing anywhere after the update, which part do I miss? * Plugin Author [loushou](https://wordpress.org/support/users/loushou/) * (@loushou) * [11 years ago](https://wordpress.org/support/topic/qr-code-not-on-pdf/#post-5776407) * Hey [@arciel](https://wordpress.org/support/users/arciel/) , * If you have tried everything in this thread and are still having problems (not only allow_url_fopen, but also the permissions solution and loopback check), then you may be being affected by a new undiscovered problem.
