In /ext/imagecycle/Classes/Plugin/CoinSlider.php you have on line 30-32
class CoinSlider extends \tx_imagecycle_pi3 {
}
which needs in our opinion to be corrected to "tx_imagecycle_pi2" as follows
class CoinSlider extends \tx_imagecycle_pi2 {
}
Interesting hereby is, that this throws only an error in TYPO3 8.7.10, but not in the previous TYPO3-Version 7.6.x.
