Fatal error when trying to activate plugin

Anyone please?

Hi,

I think you can fix that, at least until a new update of ai1ec comes out.

Line 46 relates to the following function, that is designed to check and retrieve the version of the ai1ec plugin:

public static function getAllInOneEventCalVersionNumber() {
        if (defined('AI1EC_VERSION')) {//This will be faster if available
            return AI1EC_VERSION;
        } else {
            if (!function_exists('get_plugins')) {//We need this to check version of the event cal plugin
                require_once ABSPATH . 'wp-admin/includes/plugin.php';
            }
            $pluginDir = __DIR__ . "/..";
            $pluginName = "all-in-one-event-calendar";
            $version = get_plugin_data("$pluginDir/$pluginName/$pluginName.php")['Version'];
            return $version;
        }
    }

Since it cannot automatically retrieve the version, give it manually, by telling it to just spit out a version:

public static function getAllInOneEventCalVersionNumber() {
        if (defined('AI1EC_VERSION')) {//This will be faster if available
            return AI1EC_VERSION;
        } else {
            $version = "2.2.1";
            return $version;
        }
    }

This should do the trick! (unless you have removed the version query from the ai1ec css file for browser level caching or CDN caching, like I did)
Hope this helps, cheers!

Hi infprt,

Thank you! The plugin is running now. However I did not found any speed progress. These two queries still consume a lot loading time:

?ai1ec_render_js=common_frontend&is_backend=false&ver=2.2.1
?sccss=1&ver=4.2.2

Something isn’t right then. When this plugin is working, your site never loads this:
?ai1ec_render_js=common_frontend&is_backend=false&ver=2.2.1

Instead of that js file, it loads some other like this:
/wp-content/plugins/fix-event-calendar-caching/event-cal-2.2.1-somehashcodedependingontheserverhosted.js?hash=anothershash

About the second file you mention, it’s a css file, this plugin only takes care of the js. Also, I don’t think that css file is from ai1ec plugin.

Maybe you can have a look at: https://pgzeewolde.nl/ ? I would really appriciate that.

I have tried almost everything to get the load time acceptable.

I see it working! I’ll post again soon, just let me check better.

I like your site ?? although I didn’t understood a word ehehee

I think it is very well optimized speed wise, congratz! Nice work with wpfc, way better than I’ve done.

I tested your twice, this plugin is working correctly and the js is loading in 121ms and 128ms! which is great, I wouldn’t bother no more!

The site has above 90% on speedtests and it loaded in 3.40s and 3.10s, from London. I’m in Portugal and speed seems nice too.

It’s the instagram that is slowing you site down. Your site loaded in like 2 seconds but the 4/5 lasts calls to instagram API hang for 2/3 seconds sometimes. I then tested from Canada and USA (Dallas) and those calls dropped because those locations are closer to instagram servers.

There’s seem to be something off with one of the minifications in wpfc because you minified the ai1ec_css and that file doesnt minify well, and so you views dropdown button in the agenda is showing code instead of the icon, but that’s minor. Again, nice work you got there! Cheers

Woow! Thank you for the great job you did ??
I think that I have tot be positive about the load time of the website. The only thing that bothers me is the event detail pages are not working anymore. I get 404s (with the sheep ?? ) all the time. Any idea why?

That’s strange indeed! Have you edited/translated any slug? Like changing “event” to “evenement” or something?

Have you used ai1ec from last version or did you use older versions and then updated to this one?
Try this:
Settings –> Permalinks —> Save Settings (without any changes)

Hi infprt,

Found the solution! It was another event plugin that was causing the problem. Now it’s running smooth.

Thank you!
