* Hi, folks
we have been getting some errors with PHP 7.2.5 and I have rolled
back to 7.1x to see if that might solve it; Apache, Plesk/Onyx (fully patched),
HTTP/2.
* Anyway — e.g.,
`AH01071: Got error 'PHP message: PHP Warning: A non-numeric
value encountered in /var/www/vhosts/DOMAIN.com/httpdocs/wire/assets/plugins/
pdf-print/mpdf/mpdf.php on line 30649\n'`

* apparently this line in mpdf.php
* ```
} else
$size *= (25.4 / $this->dpi); //nothing == px
```
* Changing to php 7.1 still generating error on EVERY load; so not issue with 7.1
vs 7.2.5 apparently.

* I have not tried to hack this, but it seems like updating to v7.0 vs 6.1 of mPDF
might be advisable ?
* With PDF & Print by BestWebSoft / Version: 2.0.2
* ref:
* ```
// Software: mPDF, Unicode-HTML Free PDF generator *
// Version: 6.1
```
* version 7.0.0 works up to PHP 7.2 ( < 7.3 )

* Hi,
* Thank you for contacting us and for the suggested solution.
* Our PDF & Print plugin’s work is based on mPDF library version 6.1.
We are planning
to update the mPDF library in the future. At the moment we cannot provide any
terms when it will be implemented.
* Please let us know if you have any additional questions.

* Thanks for reply.
Just for laughs, I’m going to try rolling in v7 to the plugin
to see if works or not.
* In our case, we have a news portal with 15,000 pages of content going back to
2005, even though I have pruned about 1,000 totally obsolete items this year.
Problem for us, is BING likes to ping our pages as we used to have static .txt
and .pdf files in addition to .shtml – so when we went to .php – we retired and
redirected all the old pdf and txt URLs, but now with a “save pdf’ button (we’re
using our own bootstrap button, not function or shortcode from plugin) — BING
is “pinging” the PDF and archiving it even with a rel=nofollow — so were getting
a *ton* of errors every day, as you can imagine once we moved to PHP 7.2.5 which
we had to do for our ecommerce system ….
* Anyway — can’t go back to PHP 5.6, so I love the plugin, and will see if mPDF
7x works with the plugin as-is, and report back.
* Thanks again for the awesome plugin!

* HI,
I was not able to ‘hack’ the update due to how you’re integrating that.
And also got sidetracked moving our server to HTTP/2 + ALPN.
* To revisit this… any ETA on updating this, or even starting with the PRO version,
for PHP 7 compatibility. We’re running PHP 7.2 and want to use this again, and
I was about to buy the pro version when we ran into the massive error logs issue.
* Thanks for your time – I imagine you might have better things to do, but we’d
love to see a PHP 7 ready version of this, as it’s super helpful for our company!

* Hi, I have the same issue as it seems:
* I am using Version 2.0.2 and have PHP 7.2 (hosted on 1&1) when I got this error.
I had to downgrade to PHP 7.0 to no longer get the messages (and a properly formatted
PDF). The warnings I see in the generated PDF file when using PHP 7.2 are:
* ```

```
* We are also inclined to buy a license for this plugin for our website, but if
this bug cannot be fixed by 12/2018 (which is when the 1&1 support for PHP 7.0
expires) then I’d hesitate to do so.
* PS: The print function seems to work fine in PHP 7.2 (no visible warnings at
least). So I’d guess the bug is somewhere in the PDF-related code.

* So, I modified the plugin to simply hide all errors and warnings by inserting`
error_reporting(0);` at the beginning of the _pdf-print.php_ file. I suppose `
error_reporting(E_ERROR);` would also work, because that still enables error
messages, but hides all warnings.
* PS: this is merely a **quick fix** and not a solution to the bug in the long
term…
