Some days ago, I received the latest version of LibreOffice
Version: 220.127.116.11 Build ID: 5.3.1-1 Threads CPU : 4; Version de l'OS :Linux 4.8; UI Render : par défaut; VCL : gtk2; Moteur de mise en page : nouveau; Locale : fr-FR (fr_FR.UTF-8); Calc: group
LibreOffice is working well. The problem is that suddenly three extensions stopped working with the same error message:
Erreur de syntaxe BASIC Atendu: ).
Among these extensions there is the well-known AltSearch which had been tuned for LibreOffice 5.
Not sure how to proceed now to solve this.
