RC1 frontend editevent -->0 Call to a member function format() on bool comes always back!

[jojo12]

I installed an old backup and used the step by step to arrive to JEM4 on Joomla 4. It worked well. But when I try to change something in a event with editevent (frontend), the old known error is back! What did I wrong? How can we change, that this will finish?

@jojo12 Check commit above or excecuta in mysql: INSERT INTO a8wlc_jem_config (keyname, value, access) VALUES ('flagicons_path', 'media/com_jem/images/flags/w20-png/', '0');

This error is only for migration from JEM 2.X to JEM 4.0rc1. And with this commit is solved, but you have to update the zip file.

[jojo12]

What does this mean? This is only for an update zip. Beneath that we need an other zip, which is when you install new in Joomla 4?

[mckillo]

In your migration, the _jem_config table hasn't 'flagicons_path key... This is the error. To solved, you can run the this sql line (INSERT...) to add this key. The last zip file shouled be updated with the commit, only add the new admin/sql/updates/mysql/4.0b2.sql file., So, the users do a migration, don't have the error.

Commit solve it?

Add bug remove fixed, doesn't the commit work? Does the error continue?.

[jojo12]

yes it continues

You could review to JEM setting and the datetime format ... I think that you have the old format.

[jojo12]

all dates have standard NULL

[mckillo]

IS JEm setting right too?

[jojo12]

the settings are like your image

The old backup, what have it installed? I tested agaim migration process from 2.3.6 (with sample data loaded) with JL3 to J4 with JEM 4.0rc1 and it works, after I edita and sace event and it works, not error.

[jojo12]

Has it to do that my old backup was Joomla 3.8 with JEM 2.3.3 which I updated first to 2.3.5 updated then Joomla to 3.10.11, then JEM 2.3.6, then like in the step by step.
