I did the update to version 16 today.
Unfortunately, I can no longer set the “Maximum upload size”.
The point is simply no longer available in the WebUi for me.
Manually setting the parameters in the “.user.ini”
upload_max_filesize=50M
post_max_size=50M
or
php_value upload_max_filesize 50M
php_value post_max_size 50M
in the “.htaccess”
did not help either.
No errors in the log but also no upload-limit 
Has anyone noticed a similar behavior after the update to version 16?
Can it be solved?
what is the error you got? anything in nextcloud logs? i dont know if it will help and if its really related to my latest update (to 15.0.7 however) but right now I got a permission issue that prevents me from being able to edit this using the NC interface.
chmod(): Operation not permitted at /var/www/html/nextcloud/lib/private/Log/File.php#141
So I went to the php file in question and noticed the following:
130 foreach($entry as $key => $value) {
131 if(is_string($value)) {
132 $testEncode = json_encode($value);
133 if($testEncode === false) {
134 $entry[$key] = utf8_encode($value);
135 }
136 }
137 }
138 $entry = json_encode($entry, JSON_PARTIAL_OUTPUT_ON_ERROR);
139 $handle = @fopen($this->logFile, 'a');
140 if ($this->logFileMode > 0 && (fileperms($this->logFile) & 0777) != $this->logFileMode) {
141 @chmod($this->logFile, $this->logFileMode);
142 }
143 if ($handle) {
144 fwrite($handle, $entry."\n");
145 fclose($handle);
146 } else {
147 // Fall back to error_log
148 error_log($entry);
149 }
150 if (php_sapi_name() === 'cli-server') {
151 if (!\is_string($message)) {
152 $message = json_encode($message);
153 }
154 error_log($message, 4);
155 }
156 }
Unfortunately, I’m not really good at coding. It’s even worst with php so I don’t really know what to do. Ill certainly follow your thread so I can get a better understanding of how this works.
There is no Error in the NC-logfile.
what have you entered in the ui ? 50 M ?
As I already wrote:
“The point is simply no longer available in the WebUi for me.”
Means the field no longer exists in the WebUI of my installation since the version update.
For security I have also set the theme to default. The problem persists.
But even the manual adjustments in the “.user.ini” and “.htaccess” file do not bring the expected effect. I set both values to “50M” but can upload a 100MB file. But I already wrote that in the opening article.
Can anyone explain why the “upload and memory setting” has been removed?
See it on git…
