TYPO3 Core

Now I see it happens with copying a normal content element within the same page as well. Copying that element to another page goes well.

Yeah, I guess so by now.

It also occurs if I cut / paste from one page to another, using "copy after this element"; it goes well if I use the colmn "copy here".

Extensions: flux, vhs, bootstrap_core, bootstrap kickstarter (bsdist), bscolwrap... I always used to create my own frameworks, until this time. Guess I'd better stick to my old habbits.

I'll try to test this in another install and post feedback.

Sorry to have bothered.

I have the same problem: after inserting a content element by "copy after this element", the content element disappears. In Database table tt_content the PID changes to the negative value (i.e. -1790). The new value is exactly the same as the UID of the content element (1790) we pasted after. We updated the System from Typo3 4.7 to 6.2.4 on a PHP 5.5.9 server with MySQL 5.5.

Our first thought was a complication with gridelements 3.0., but the error occurs after deleting the extension completly. Actually these extensions are installed: t3colorbox 3.0.0, macina_searchbox 2.2.0, t3s_headerslider 3.0.2, tw_rssfeeds 2.1.4, realurl 1.12.8, wec_map 3.1.1, nwt_imagecrop 0.2.1, tinyaccordion 2.0.0, cal 1.6.0, flux 7.0.0, flux_galleria 2.0.0, t3jquery 2.7.1, tt_news 3.6.0.

Update: While comparing my list to the extensions installed by Vincent, the only accordance is the extension flux. After deinstalling flux and flux_galleria, "copy after this element" functions without an error!

I also use the "flux ecosystem" and I've had several issues with cut&paste or drag&drop, esp. with old versions.

Do you think this could be closed (see the comment of Sonja Fischer-Wambsganß) ?
