Upgrading Drupal

Hi Guys,

I have a Drupal 5 site that has SOLR search engine disconnected. Also simplepie module is not extracting images from its parsed articles correctly. Please guide me how can I debug this and fix this.

Thanks in advance.

I accidentally deleted a modules folder. How do I know which modules have been installed? Earlier in the Drupal 7, I could see it in the database table "system" how to be now?
I speaking about Drupal 8.

Hi,

I am trying to upgrade Drupal to 7 or 8 but I can´t, it always give me errors.
I am tired of spending my time trying to upgrade Drupal.
I wonder why people terminates Drupal 6 without a real migration solution that works.
Why develop Drupal 8 if we can´t migrate to it? Why is it not automated?
I was suposed to use Drupal to make things easier to have a site but I am being forced to understand Linux, PHP, Drupal structure and other stuff I read but don´t understand a thing...

I recently upgrade my sites to 7.50, Things seemed to be working OK after I did the upgrade, now I am suddenly getting a "HTTP ERROR 500" message with the sites. I did my usual backing up of the sites before upgrading, then after I was sure things were working AOK, I would delete the backups. SO now I have no backup of the previous version. After I discovered the problem, I installed 7.50 onto another site that I hadn't been using for anything outside of email. When I went to look at the site the same error was there.

When I try to update from 8.1.3 to 8.1.4 or 8.1.5 (I delete everything except modules, sites and themes) and immediately after pointing to update.php I get white blank screen and in Apache 2.4 error log following error:
[proxy_fcgi:error] AH01071: Got error 'PHP message: PHP Fatal error: require(): Failed opening required /core/modules/user/src/UserServiceProvider.php (include_path='.:/usr/share/pear:/usr/share/php') in /vendor/symfony/class-loader/ApcClassLoader.php on line 110

What is the stable drush version for drupal 8?
