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
