Small changes on the website on Presta

Accelerated site there were a few problems:

1) In the categories is missing for more description below - https://starter.net.ua/25-starter-opel and so in all. It is necessary there is a video it is also necessary. It is the module additional description. In it all data are preserved, but not displayed.

2) From the admin panel missing module reviews. On hosting is, tried to reinstall on a straight line, everything works but missing the already existing comments on the site, it is important not to lose.

3) custom callback module disappeared from the home and everywhere. In the admin there.

4) Stopped working module, quick order.
