Downgrade 1.10.11 / 2.0.5 to 1.10.9

Line with this error: self::$_instance->set_defaults(); // set default settings

Please… Anybody help me?

Hello,

This usually means incorrect installation or upgrade. Please reinstall the calendar Just follow the steps in the article to ensure that you don’t lose your events: https://support.time.ly/manually-upgrading-the-calendar/

If this doesn’t help then solution is :
Database -> wp_options, click option_name to sort and delete everything with ai1ec_, this will delete plugin settings but events will remain in the database and the plugin will be able to re-install.

Hope this helps.
Take Care

Hi Jsshan…

I did the following:
1) deleted file uninstall.php
2) I clicked DELETE (instead of DISABLE). maybe my mistake
3) delete ALL MySQL tables with ai1ec_ prefix
4) upload 1.10.9 standard version
5) copy the folder themes-ai1ec to wp-contente
6) I tried to activate the plugin…
Return: Fatal error: Call to a member function set_defaults() on a non-object in /home/storage/d/e1/6b/guiagerais1/public_html/wp-content/plugins/all-in-one-event-calendar/app/model/class-ai1ec-settings.php on line 439

A second attempt, I bought the pro version 1.11.5…
Return: Fatal error: Call to a member function set_defaults() on a non-object in /home/storage/d/e1/6b/guiagerais1/public_html/wp-content/plugins/all-in-one-event-calendar/app/model/class-ai1ec-settings.php on line 665

ie, anything decided to buy another version because the error seems to be caused by the same reason: Fatal error: Call to a member function set_defaults() on a non-object in …

I’m sorry by my poor english

Jashan… Thank you so much!

I deleted everything with ai1ec in wp_options and works!

I thought it had worked, but it did not work …

Ai1ec_Database_Schema_Exception thrown
Failed to perform schema upgrade

Version 2.0.5 return:
Fatal error: func_get_args(): Can’t be used as a function parameter in /home/storage/d/e1/6b/guiagerais1/public_html/wp-content/plugins/all-in-one-event-calendar/lib/exception/handler.php on line 164

I delete all files, remove fields with a11ec_ and version 2.0.5 install… But All-in-One Event Calendar Facebook Integration by Time.ly return a blank page…

I installed version 2.0.5 + addons (with all-in-one-event-calendar-facebook-integration_1.0.6-1)

But…

Don’t show any events on agenda page…
I honestly quit using any update of this plugin
how to get to spoil something good and working?

Now I’m trying to get back to the version that was running before any upgrade and so many problems … Version 1:10:11 …

Deleted file uninstall.php
removed the all addons
removed 2.0.5
remove all records with a11ec_ on wp_options table
I sent the backup folders and files via FTP (Version 1:10:11)
but when trying to activate the plugin gives error…
Fatal error: Call to a member function set_defaults() on a non-object in /home/storage/d/e1/6b/guiagerais1/public_html/wp-content/plugins/all-in-one-event-calendar/app/model/class-ai1ec-settings.php on line 474

and now???

Thanks

Jashan,

Version 1.10.9 it’s working now…
But I needed to re-register my events.
Aat least it’s working now!

How do I do to remove update warning to 2.0.5 in my admin panel?

Hi,

I’ve got the same problem:
Fatal error: Call to a member function set_defaults() on a non-object in /home/mk/www/www-root/wp-content/plugins/all-in-one-event-calendar/app/model/class-ai1ec-settings.php on line 306

I’ve tried everything above except for “Database -> wp_options, click option_name to sort and delete everything with ai1ec_, this will delete plugin settings but events will remain in the database and the plugin will be able to re-install.“
How do I get to Database -> wp_options???

BR,
Mikael

FYI, I have Version 1.10.5.
My problems started when trying to upgrade to 2.0.5…

I have always had a lot of issues when upgrading All-in-one Calendar…

Hello Ramon,

If you are reentering your events, I would suggest that you clean install 2.0.5 and then enter the events.

Thanks
