Problem with vmrouterhelper after upgrading to Joomla 3.6.3

[Dionysos]

The error received is:
.... PHP Fatal error: Cannot redeclare class vmrouterhelper in /xxx/xxx/public_html/components/com_virtuemart/router.php on line 713

The site returns HTTP ERROR 500

Here exactly the same problem after receiving first a http 500 error in the front end. Back end OK. The VM version is 3.0.18

Same Issue here after upgrade from J! 3.6.2 to 3.6.3
"PHP message: PHP Fatal error:  Cannot redeclare class vmrouterHelper in /components/com_virtuemart/router.php on line 646" while reading response header from upstream
VM Version 3.0.18

Digging a bit deeper....

Fatal error: Cannot redeclare virtuemartBuildRoute() (previously declared in /components/com_tcpdf/router.php:23) in /components/com_virtuemart/router.php on line 293

I had tcpdf 1.0.0 installed, I got a notice that tcpdf 1.0.2 was available however this was not updating via Normal Joomla Update. I removed the tcpdf package, and all was well with my site....

Now just need to get tcpdf 1.0.2 installed....

Hope that helps someone

This didn't work on my original issue.

All I can suggest is to set and review your PHP error logs.

[Milbo]

com_tcpdf has no folder in the frontend and there is also no router.php in it. Did you start with a backup/qhickstarter package of a template? I wonder how comes the router file of virtuemart to a com_tcpdf folder and why it is loaded?

[bestcons]

I checked my tcpdf version. It is already on 1.0.2. so this does not seem to be the root cause.

I'm getting the same issues, but my tcpdf displays an error of "component not found", but the folder is there with all the files.
Any suggestions?

[tabbu]

My problem was solved as suggested by RichIT, thanks very much for your post.

I switched off tcpdf 1.0.2 but the problem persists.

As Max says there is no tcpdf in the FE on current installs

at a guess this is left over so just rename the folder  /components/com_tcpdf/   to   /components/com_tcpdf___/

if that fixes it delete the folder
