in the settings.php you can enable phpinfo if you then go to https://yoursite/phpinfo (as a site admin) you can see the effective limits. Are those the same?

They are exactly same with the ones I edited, Jerome. I use easyphp on windows as localhost.

1 - Check your error log.

2 - Try uploading this file of the same size through the File plugin instead of pasting it into the visual editor. What's happening?

According to my experiments, images larger than 1.5MB cannot be uploaded using ckeditor although post_max_size = 15M and upload_max_filesize = 13M in both php.ini and .htaccess files

And I tried to upload a jpg file of 2,5 MB through the files it produces "Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 16384 bytes) in G:\easyphp\EasyPHP-Devserver-17\eds-www\elgg-latest\vendor\imagine\imagine\src\Gd\Image.php on line 763""

When check the error log via Develop, Error log is empty.

1 - Try to increase 'memory_limit' param in php.ini (fpm and cli both)

2 - Install Imagick and use this library instead of GD.

Read this to understand your problem

Thanks Nikolai,

Increasing memory_limit from 128M to 256M in php.ini solved the problem

Hi again,

I use Elgg 5.1.2, that is the latest version, on easyphp server on my computer. Saving a blog results as a draft work even I choose "published" while saving. Is that only me I suffer?

I found out that the previous version of  "blog_tools" caused that issue. After updating the plugin v18 it solved the problem.
