Problems updating Joomla 3.4 to 3.6

[nagehoko]

Hello Forum,
Firstly, Happy Holidays and a prosperous new year;
Secondly infinite thanks for this great support
And now to the question, apologize for my bad English but I will try to explain myself well
My website is a Joomla 3.4 with Virtuemart 3.0.18; Working perfectly both Joomla and Vm
When I have tried several times in this last year, updating to J 3.6.x everything is very fast in the Joomla part, but the access to Vm is impossible giving error in the FrontEnd; However in the Backend is still all Vm, allowing its management and access to all its options
I always finish doing a restoration from a backup of my Hosting "Webempresa" and everything is as before
Is there any solution?
I reiterate my gratitude and await your instructions

but the access to Vm is impossible giving error in the FrontEnd;

without the error unlikely anyone can help

[nagehoko]

Apologies for expressing myself so poorly
The error consists in, once updated the Joomla version of v3.4 to v3.6, when clicking in the superior menu "Tiendaonline" (link to the main page of Vm) only leaves a blank screen with the error 500
In the Backend of Joomla the Vm program is still installed, allowing access and change configurations. But in FrontEnd, part of the user only leaves the commented blank page. The rest of the website works perfectly.
I can not include images because the system of this forum tells me that I have the folder full and that I contact the administrator
Thank you for answering, I hope your instruction instructions

leaves a blank screen with the error 500

then you must find the 500 server error

Thank you for your quick response, I have searched the indicated files and the following texts are the ones listed in them, as I have not been able to add images I paste them into text.
Sorry but I do not interpret what these lines of code say, can you help me?

If friend, I use it but if I can do without if it is the cause of the problems, this is the description that surely you know

Maybe changing any of your settings would not make a mistake?


ARI Cloud Carousel module based on Cloud Carousel jQuery plugin and provides possibility to create awesome 3D image carousel based on images from specific folder(s)


The link of your last message I did not understand it very well, I spoke of UNICODE letter errors ... I do not understand it I'm sorry

I wait for your news thank you very much

[nagehoko]

I just disabled the module "Ari" and proceeded to perform the joomla upgrade; Now everything works perfectly
Joomla 3.6.5 with Vm 3.0.18

Thank you very much for all your time and wisdom, without you it would be impossible, thank you

Is there any compatible alternative, to put a carrousel of images, is something simple but gives a lot of view to the pages?

What can I do to thank you for your help and dedication?

[GJC Web Design]

As I read it it should be fixed in the latest ari release of this slider

If not you can PM or email me and I can fix the problem
