Tempo di preghiera

Thanks Joe. I hope you can solve it, I really like your calendar. I’ll wait a bit also because I don’t know if I can do the procedure you indicate to recover the calendar data. Thanks for your support

As I already wrote here, I installed the query tracking plugin you suggested, this is the error it gives me:
Warning: foreach() argument must be of type array|object, string is provided wp-content/plugins/my-calendar/my-calendar-core.php:910 mc_admin_head() wp-include/class-wp-hook.php:324 do_action(‘admin_head’) wp-admin/admin-header.php:163 1 Plugin: my-calendar
It doesn’t say anything else. This on the test site that I use for testing and which is completely identical to the real site, only the hosting changes: the test site is on Altervista, while the real site is on Aruba.
If I install the update on the real site, everything goes haywire and I have to backup the entire site to restore everything. While on Altervista the problem is less because wordpress lets me access the administrative panel and I can deactivate the plugin without consequences for the site. I think the problem is in the hosting that I use for the site. So I think the only alternative is to abandon this plugin and put another one. The only thing is that I would like to recover all the data that I have already entered on My Calendar: is this possible?

I updated on the site I use for testing and which has the same theme and plugin. Nothing to do, WordPress blocks the entire site telling me that it is in error. Therefore the site cannot be used with the active calendar plugin. I’m so sorry I can’t resolve this, I’ll be forced to use another calendar plugin. Is there a way to export the data entered into your plugin so you can insert it into the new one? There are many events, and it would be a lot of work to insert them again by hand. I’m saddened because I really like your plugin

Yes that’s the only mistake I see. But the site goes into error and wordpress blocks my entire site, telling me that there is an error generated by the calendar plugin that I cannot update. I use Version 3.4.24 if I update everything goes haywire

Thanks for the attention. The problem occurs, on the test site, when I install and activate it. From the control panel everything seems fine but, when I go to the home page of the site, the site disappears, an error message appears from wordpress saying: A critical error has occurred on your website.

On the tempodipreghiera.it website I don’t try to update the plugin, because last time I had to restore the entire site with a backup. I hope you can understand what makes the plugin go haywire.
