Invoices created but not downloading

Hi EE,

We are running into an issue with invoices not downloading at all. The invoices html is created, but clicking on the download button does nothing except getting WordPress stuck in a loop. The only way to get out of the loop is by restarting the browser.

Using a default invoice template throws the same error and logging with WP_DEBUG doesn’t give any information. Troubles started when we tried uploading an invoice logo. No logo is selected at the moment.

Hope you can help, thanks.

Hi there,

WP_DEBUG may be too late to log the error, can you check the servers error logs and see if there are any errors there?

Also, check that allow_url_fopen is enabled on your server and are you running any security plugins on the site?

Hi Tony,

It’s taking its time to get a response from the server people, but they have enabled allow_url_fopen and things haven’t changed. Still trying to get a response re: server errors. In the meantime, anything else we can try?

Some web hosts make those server error logs available via the hosting control panel (oftentimes called C-Panel). If you can access the server error log that way, can you compare the errors logged at the time you tried to get a PDF invoice?

Hi –

We’ve done some troubleshooting and think this is related to the SSL certificate on our website. The certificate was disabled for a moment and invoices downloaded correctly. Is there a way to bypass ssl when downloading the invoices?

Not really, the URL’s are built using WP core functions which will use SSL if available.

How are you enabled SSL on the site?

We’re still looking for a bug somewhere, but the certificate is installed in the vhost of Apache2. It’s a Let’s Encrypt certificate.

Does that info help?

Are you using a plugin to set the site to load over HTTPS or relying on a redirect?

For example, you could try the Really Simple CSS which switches the site to use HTTPS and make sure any plugins use HTTPS rather than HTTP (to then be redirected by the host).
