EnglishHello/Hi/Greetings,
Hello,
I have uploaded some jpg files to my website. I wanted to edit or rotate these images in Oiwigo as an administrator. When I use the pen to edit, I get the following message:
Fatal error: Uncaught Error: Call to undefined function str_starts_with() in /var/www/virtual/mc-weber.de/htdocs/admin/include/functions_metadata.php:195 Stack trace: #0 /var/www/virtual/mc-weber.de/htdocs/admin/include/functions_metadata.php(292): get_sync_metadata(Array) #1 /var/www/virtual/mc-weber.de/htdocs/admin/picture_modify.php(74): sync_metadata(Array) #2 /var/www/virtual/mc-weber.de/htdocs/admin/photo.php(68): include('/var/www/virtua...') #3 /var/www/virtual/mc-weber.de/htdocs/admin.php(407): include('/var/www/virtua...') #4 {main} thrown in /var/www/virtual/mc-weber.de/htdocs/admin/include/functions_metadata.php on line 195
Unfortunately, I don't know what to do with this. Does anyone have any ideas?
I hope I'm in the right place in the forum.
Thanks,
Michael
Addendum: I am using version 16.0.

Assuming you are using PHP 7.4 then there is currently an issue with Piwigo 16 on PHP 7.4 and the use of the built-in function str_starts_with() as shown in the error message. I expect it will be fixed in an update but in the meantime if you are not able to switch to a higher version, then you can also use a polyfill in the personal plugin to fix this problem.

You are probably using PHP 7.4. You can try the solution proposed in this post while waiting for version 16.1.0 to be released: [Forum, post 193380 by moberley in topic 34552] Can't upload photos since update to v16..

Thanks for your help, you're right of course, I'm using PHP 7.4.

Hello,
I just saw that I could select a PHP version for my homepage.
Which version should I choose: 8.1, 8.2, 8.3, or 8.4?
Best regards, Michael

I am using PHP 8.4 with Piwigo 16 so the highest available there should work fine as far as I know.
