module not working at all with Drupal 8.6

Hello Lauren.

Can you use the version: 8.x-2.1, please?!

https://ftp.drupal.org/files/projects/modal_page-8.x-2.1.zip

This version is stable and works good for Drupal 8.6+

Any question please comment, okay?!

Best,

@laurencefass; after your testes tell me if version: 8.x-2.1 works good for you.

Good Work and Good Week.

Thank you very much.

Best,

I can attest that ver 8.2.1 does not work w. D8.6.3 - except for one site (out of 3). It must be a conflict with other modules or themes (I guess). No log messages either.

On further thoughts: The one site working is an older install, so Drupal has been upgraded several times, whereas the two non-working sites are fresh installs. Maybe (therefore) it is in the settings or htaccess files, which I do not upgrade/update.

Update:
I installed D8.6.3 with an old (march 2016) default settings.php file and module works fine in Bartic.
However installing bootstrap-based themes interfere with the module so that the modal pop-up show wrong text etc and will lock up the site.

In other words: There are conflicts with other modal modules or code/script. The module does not function with the new settings.php file.

Further testing.
With bootstrap javascript modal disabled (bootstrap3 theme) module works, but does not look completely correct.

Please, try the new release and in case of theme bootstrap disable load JS Bootstrap (bootstrap.min.js).

Look:

Sorry, the update crashes my site with:
Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'base.body__value' in 'field list': SELECT base.id AS id, base.uuid AS uuid, base.title AS title, base.body__value AS body__value, base.body__format AS body__format, base.type AS type, base.pages AS pages, base.parameters AS parameters, base.ok_label_button AS ok_label_button, base.langcode AS langcode, base.created AS created, base.changed AS changed FROM {modal} base WHERE base.id IN (:db_condition_placeholder_0); Array ( [:db_condition_placeholder_0] => 1 ) i Drupal\Core\Entity\Sql\SqlContentEntityStorage->getFromStorage() (linje 388 af /home2/rudbecks/d8b.sensistop.dk/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

I was able to get the earlier ver. to work by overriding CSS & disablind bootstrap modal js.

I tried new ver in another install w. another theme (quatar) and disabled bootstrap js as per your advice. I get 'unexpected error' when trying to go into modal-page and log gives:
Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'base.body__value' in 'field list': SELECT base.id AS id, base.uuid AS uuid, base.title AS title, base.body__value AS body__value, base.body__format AS body__format, base.type AS type, base.pages AS pages, base.parameters AS parameters, base.ok_label_button AS ok_label_button, base.langcode AS langcode, base.created AS created, base.changed AS changed FROM {modal} base WHERE base.id IN (:db_condition_placeholder_0); Array ( [:db_condition_placeholder_0] => 1 ) i Drupal\Core\Entity\Sql\SqlContentEntityStorage->getFromStorage() (linje 388 af /home2/rudbecks/d8.sensistop.dk/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

Egmund, it is necessary to rebuild the entity, but I do not know if it is advisable in your case, which already has modals.

Thank you thalles. I will try that.

After un-installing, clearing cache & installing - errors are gone.
However; the modal popup does not show. It has an element style of 'display: none'. Where do I correct that?

Update: If I uncheck 'do not load bottstrap - - -', then it shows. --Does not make much sense to me.

This option is for those who for some reason already loads the bootstrap js.

Example: If you use a bootstrap-based theme.
