Hello,

no, there have not been any records of such a behavior for the module.
However, on another product, after upgrade to Joomla 3.4, the external library had to be re-installed.

That may just be what happened to you and that is the only thing that could 'break' the site (I assume you get a blank page for you to say that). Please try re-installing the library (changing server debugging mode could help see what is the PHP error and therefore help understanding what to fix).

I forgot to add: you did not mention from what version you were updating. v1.5 of the module requires you also update the external library, as explained in the release history. That may just have been your issue...

Hello,

many improvements have been made in the latest versions of Trombinoscope Extended and LNEE in order to minimize server response (stylesheet caching, image search in articles limited to intro text for LNEE)...
So you would probably benefit from using those versions and use those features if you are not doing so already.

In the meantime, all modules created by SYW are tested and are meant to work together on a same page.

I would need more information about your site to even start to diagnose and find a solution in your case. What is your case scenario? What extensions are you using and with what versions? Can I access your page?
